A year ago, in our November 2023 call, I said the company's priorities for 2024, we're driving R&D programs to further differentiate our unique and connected portfolio to extend our leadership at key inflections that enable future industry growth, making operational and supply chain improvements to better serve customers and drive productivity across the enterprise and ensuring that we scale the company in ways that are sustainable and environmentally responsible. Over the past year, we've made significant progress in all these areas. We strengthened our position at major inflections in logic DRAM and advanced packaging. We delivered double-digit growth in our parts and services business.

We made improvements to our operations and supply chain that supported strong cash flow and margin performance, and our key strategic initiatives are on track, including the build-out of our EPIC collaborative R&D platform and the deployment of our Net Zero playbook. In my prepared remarks today, I'll talk about three key topics: First, how large-scale secular trends are driving growth and innovation in semiconductors and why energy-efficient computing is emerging as a unifying driving force for the industry; second, how the major device architecture inflections that make up the semiconductor industry's road map are increasingly enabled by innovations in material science and materials engineering where Applied has clear leadership; and third, as the industry road map becomes increasingly complex, how we are creating incremental growth opportunities for the company to offer new solutions with our unique and connected portfolio our high-velocity collaborative R&D platform and our advanced service products. In the coming years, we are going to experience the biggest technology changes of our lifetimes with major advances in automation and robotics, electric and autonomous transportation, clean energy, and artificial intelligence. All of these tectonic shifts are made possible by semiconductors, and this provides a catalyst for the semiconductor industry to create and capture more value than ever before.

The biggest tectonic shift is AI, which has virtually endless applications and therefore, the potential to transform almost every area of the economy. Deploying AI at large scale will require AI computing to be significantly more energy efficient than it is today. To realize the full potential of AI, the leading AI companies are talking about the need to drive a 10,000 times improvement in computing performance per watt over the next 15 years. To deliver energy efficiency improvements of this magnitude, evolutionary innovation will be insufficient.

Instead, we see a new technology road map emerging made up of multiple device architecture inflections in logic, memory, and advanced packaging. This creates three significant opportunities for Applied to deliver more value to customers and extend our differentiation in the market. First, we have built a broad, unique, and connected portfolio of highly enabling technologies that we can supply to customers as co-optimized and integrated solutions. By combining adjacent process steps, such as material deposition, etch, and material modification into an integrated system, we are providing chipmakers innovative and comprehensive solutions to enable their energy-efficient architecture inflections.

Integrated solutions account for around 30% of our Semiconductor Systems revenue, and we expect them to become an even larger part of our portfolio in the future. Second, we are driving earlier and broader collaborations with our customers and partners to bring next-generation technology to market faster. Our global EPIC platform that we will build out over the next several years is specifically designed to accelerate cycles of learning, increase mutual success rates, and improve investment efficiencies. In the U.S., construction of the EPIC Center in Silicon Valley is well underway and on track to come online in 2026.

And we will share more details about our EPIC advanced packaging strategy at a technical summit we are hosting for R&D leaders next week in Singapore. And our third key opportunity is in services, where we are focused on helping customers manage increasing complexity in their business as the industry scales. We are deploying our advanced service products to help them accelerate their R&D, speed up transfer of new chip technologies from lab to fab, and then optimize device performance, yield, output, and cost in high-volume manufacturing. This is supporting double-digit growth in our parts and service business with a high percentage of these revenues coming from subscriptions in the form of long-term agreements.

These subscriptions have a high renewal rate, and the average tenure of the agreements is growing. This year, we signed our first 5-year service agreements with multiple customers. Overall, AGS delivered a record quarter, a record year in their 21st consecutive quarter of year-on-year growth. Across the business, we are translating opportunities into results as major device architecture inflections grow our available market and we gain share through the technology transitions.

In 2024, the leading-edge logic companies started moving the first gate-all-around nodes from their R&D pilot lines into high-volume production. We generated more than $2.5 billion of revenue from these advanced nodes in the fiscal year and expect those revenues to approximately double in 2025. Overall, the transition from a FinFET-based node to node with gate-all-around transistors and backside power distribution grows Applied's available market from around $12 billion to approximately $14 billion for every 100,000 wafer starts per month of capacity. We also expect to capture more than 50% of the process equipment spending for the gate-all-around nodes up from the mid- to high 40% range for FinFET generation fabs.

In DRAM, our revenues also grew significantly in fiscal 2024, up more than 60% year on year. Compute memory is a critical technology for AI data centers, and DRAM makers are accelerating their capacity plans, especially in high-bandwidth memory, where high-performance DRAM dies are stacked and connected to a logic die with advanced packaging. The dies used in high-bandwidth memory are much larger than standard DRAM, which means that more than three times the wafer capacity is needed to produce the same volume of chips. On top of this, the packaging steps needed for die stacking further increased our available market.

In fiscal 2024, our HBM packaging revenues grew to more than $700 million. DRAM is a great example of how our inflection-focused innovation strategy is succeeding. By focusing on the most enabling steps for next-generation technologies, Applied has increased our share of the DRAM market by around 10 points over the past decade. Future DRAM inflections will further expand our available market as next-generation 4F squared and 3D DRAM architectures are even more materials engineering intensive.

Advanced packaging is another major device architecture inflection that provides significant improvements in the performance, energy consumption, and cost of next-generation chips. We have been investing in new technology to enable advanced packaging for more than a decade, establishing strong leadership positions in micro bump and through-silicon via. In fiscal 2024, our overall advanced packaging product portfolio generated close to $1.7 billion of revenue, up three times in the last four years. We believe this business will double in size in coming years as heterogeneous integration is more widely adopted and we introduce new solutions that grow our addressable market.

Gate-all-around transistors backside power distribution, 4F squared and 3D DRAM, advanced packaging and next-generation power semiconductors are all examples of device architecture inflections that are enabled by materials engineering. As a result, materials engineering, which spans all the technologies needed to deposit materials, remove or shape materials, and modify the property of materials at an atomic level, is growing as a percentage of overall equipment spending at advanced nodes. Before I hand over to Brice, let me summarize. In fiscal 2024, Applied grew revenue and earnings for the fifth consecutive year.

We strengthened our position at the key technology inflections that customers will ramp in volume production over the next several years. We delivered double-digit growth in parts and services, and we drove operational performance improvements across Applied and our supply chain. As we look ahead to 2025 and beyond, we see AI and energy-efficient computing remaining the key driver of innovation in the semiconductor industry. And the industry's road map becoming increasingly dependent on materials engineering, which grows Applied's addressable market and provides a tailwind for us to outperform through the investment cycle.

I strongly believe that Applied Materials has the right capabilities, strategy, and partnerships at the right time, and this puts us in a great position for the future. We are delivering differentiated solutions to our customers to help them win the key device architecture inflection races. We are strengthening R&D collaboration with customers and partners to drive innovation and commercialization velocity and optimize mutual success rates. And we are growing our service business by helping customers manage increasing complexity as the industry scales.

Now, I'll hand over to Brice.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Thanks, Gary, and thanks to everyone joining today's call. We had a strong fiscal 2024, delivering record revenue and earnings per share, generating healthy operating cash flow, and distributing over $5 billion to shareholders via dividends and share repurchases. I would like to thank the entire Applied Materials team for their hard work and execution which enabled us to achieve these excellent results. For the full fiscal year, net sales were $27.2 billion, up 2.5% on a year-over-year basis, with growth in all three business segments.

Non-GAAP gross margin was 47.6%, up 80 basis points year over year and our highest annual gross margin rate since fiscal 2000 as we optimized our operations and made progress on value-based pricing. On a year-over-year basis, non-GAAP operating profit grew 2.7% and non-GAAP operating margin was up 10 basis points. Non-GAAP earnings per share grew 7.5% year over year to $8.65. For fiscal Q4, net sales were $7.05 billion, up nearly 5% on a year-over-year basis, driven by solid growth in Semiconductor Systems and Services.

China declined to 30% of revenue, in line with our previously communicated expectation and our historical average. Non-GAAP gross margin was 47.5%, up slightly on both a year-over-year and quarter-over-quarter basis, driven by a favorable mix and operational improvements, offsetting headwinds related to the lower China revenue. Non-GAAP operating expenses were $1.28 billion or 18.2% of revenue and roughly in line with our expectations as we prioritized funding long-term strategic programs. Non-GAAP earnings per share was a record $2.32, up 9% year over year and benefiting from higher gross margin, higher interest income, a lower effective tax rate, and share repurchases.

Turning to the segments. Semiconductor system sales were $5.18 billion for Q4, up 6% year over year, driven by leading-edge foundry-logic demand. Non-GAAP operating margin was 35.4%, down 50 basis points year over year, given the normalizing China mix. DRAM sales declined 10% year over year, given the elevated purchases from China in Q4 of fiscal 2023.

NAND sales were flat year over year. Foundry-logic sales increased 12% year over year, fueled by robust growth at the leading edge, including increasing investments for gate-all-around nodes as customers invested to enable critical technology inflections. Sales for the ICAPS nodes, which serve customers across the IoT, communications, auto, power, and sensor markets, were down year over year, given high demand in the year-ago period. Moving to Applied Global Services, AGS delivered record revenue of $1.64 billion in Q4, up 11% on a year-over-year basis and driven by robust growth in services, partially offset by a decline in 200-millimeter equipment sales.

Non-GAAP operating margin of 30%, was up 2.7 percentage points year over year, and non-GAAP operating income was a record $492 million. Year over year, we saw increases across many operational metrics, including a 7% increase in the installed base and a 10% increase in tools under service agreements. Our average contract length increased to 2.9 years, and we maintained a renewal rate of greater than 90%. Lastly, our display business generated revenue of $211 million, in line with our expectations as the industry experienced lower investment levels, amid ongoing weakness in end market demand.

Over time, we expect there to be an increase in capital investments to support the adoption of OLED technology and IT devices like notebooks, PCs, and tablets. We are well positioned to enable customers for the coming OLED IT inflection with our technology. Moving to the balance sheet and cash flows. We ended the quarter with cash and cash equivalents of $8 billion and debt of $6.3 billion.

Cash from operations in the quarter was $2.6 billion. Capital expenditures were $407 million and free cash flow was $2.2 billion. In total, we generated $8.7 billion in operating cash flow and $7.5 billion in free cash flow in fiscal 2024. We distributed $1.8 billion to shareholders in the quarter, including $329 million in dividends and $1.4 billion in share repurchases.

For the full year, we distributed $5 billion to shareholders, of which $3.8 billion was through share repurchases, up 75% from $2.2 billion in fiscal 2023. As of the end of the quarter, approximately $8.9 billion remains available under our share repurchase authorization. As we contemplate fiscal Q1, we are seeing strong demand in leading-edge logic and the ICAPS nodes and sequential growth in memory. With that in mind, let me share our outlook for fiscal Q1.

We expect total revenue of $7.15 billion, plus or minus $400 million, and non-GAAP EPS of $2.29, plus or minus $0.18, both representing an increase of approximately 7% on a year-over-year basis. We expect Semiconductor Systems revenue of approximately $5.3 billion, which is up 8% year over year; AGS revenue of approximately $1.65 billion, which is up 12% year over year; and display revenue of approximately $175 million. We expect non-GAAP gross margin of approximately 48.4%, driven by a favorable mix and cost and pricing improvements, and non-GAAP operating expenses of approximately $1.33 billion. We are modeling a tax rate of approximately 14%, and our outlook is consistent with trade rules currently in effect.

In closing, we had a strong fiscal 2024 with momentum across the majority of our markets, fueling record revenue and earnings per share. Our portfolio positions us to uniquely capitalize on the secular megatrends shaping the technology landscape from data center and AI to edge computing, the Internet of Things, and display. Underpinning this is our strong investment-grade balance sheet, solid cash generation, and healthy shareholder distributions. Operator, we are now ready to begin the Q&A session, please.

Questions & Answers:

Operator

Thank you. We will now open the line for questions. [Operator instructions] As we compile the roster, we request that you please limit yourself to one question each to enable us to reach as many participants as possible during today's call. One moment for our first question.

And our first question comes from the line of Stacy Rasgon from Bernstein Research. Your question, please.

Stacy Rasgon -- Analyst

Hi, guys. Thanks for taking my questions. The first one, I wanted to ask what you're seeing or expecting for China mix as we go through next year. And I guess, there was a little surprise you suggested you saw ICAPS strength going into Q1.

Do you think -- I guess maybe you can talk to us about how that ICAPS strength in the near term splits out between China and rest of the world and how you see China mix either sustaining at 30% or moving off that number as we go through next year.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Great. Thanks for the question, Stacy, and hello. Yeah, the China mix, a couple of signals there. So, 30% in Q4 as we reported, and that's normalized and come down after we serve that China DRAM demand that we had in earlier quarters.

Our outlook in Q1 is -- also contains approximately 30% for the China mix. When we think about ICAPS across the world, it is still very healthy. So, we said it's lower than our prior Q4. So, Q4 of '24 was a little bit lower than Q4 of '23, but the ICAPS market is still very healthy.

And it's healthy globally. It's healthy in China, and it's healthy across the world from a total level perspective. Having said that, we expect the ICAPS markets to grow over time. We've talked about mid- to high single digits at the device level.

We expect customers to continue to add capacity. There are signs to watch for. There are slower end markets in ICAPS. Automotive, industrial, analog, image sensors are all markets that have been slower.

So, we've kind of been looking to see if the investment rate would go a little bit lower. But as far as our Q4 and our Q1, it remains strong.

Stacy Rasgon -- Analyst

Got it. Thanks. And for my follow-up then, if China mix isn't going up, gross margins are, so it doesn't sound like the gross margin increase is due to an increase in China mix. So, can you talk about the drivers of that gross margin increase into Q1? And I guess, maybe talk to sustainability as we go through next year.

Like, do you think you get back closer to the target ranges for gross margins as we go through the end of the year?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yeah. Thanks for the question on that. So, our gross margin, the way we want to shape that from your modeling perspective and where the business is, we think our underlying rate has improved to about 48% at this point. So, it has improved, and that's -- we've made improvements top to bottom in the business, logistics, our inventory management, scrap management, cost overall, and our implementation of value pricing.

So, a lot of elements working on the gross margin equation. In Q1, in particular, it's -- we're guiding 48.4%, so above that 48% sort of baseline, and that's based on really strong product mix that we have in Q1. So, we think 48% is the right level for you to think about longer term, and we'll, of course, continue to work on improving that.

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Yeah. Stacy, this is Gary. One of the things also that we're very focused on is winning the inflections. There's a lot of really great inflections that provide a tailwind for Applied.

And we're bringing enabling technology to our customers in a number of different markets. So, one thing that is also a tailwind for us is pricing improvement as we're shipping more valuable products. So, that's part of what you're seeing in that increased gross margin. And I think that we have a great opportunity to continue to drive that going forward.

Stacy Rasgon -- Analyst

Thank you, guys.

Operator

Thank you. And our next question comes from the line of C.J. Muse from Cantor. Your question, please.

C.J. Muse -- Analyst

Yeah. Good afternoon. Thank you for taking the question. I know you guys don't want to talk about WFE, but I was hoping you could speak to it directionally.

How are you thinking about '24 -- '25, more importantly, growth? And maybe perhaps more importantly, in terms of the change in the administration, how you're thinking about the potential risk in terms of added restrictions or perhaps going the other direction. Would love to hear your first thoughts there.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

OK. Thanks for the question, C.J., and thanks for staying up for us. So, on the WFE, directionally, for '24, so we just closed our fifth year of growth. So, we'll see what the print is across the whole industry, but we would expect it to have shown growth.

And then for '25, if you zoom out, we're talking about $1 trillion semiconductor industry by 2030. I think that's consistent across most of the industry having that view. And we certainly have that view given the added wafer starts and added capacity across the industry basically every single year. So, it's hard to guarantee '25, but I'll just call out that our Q4 was growth year over year.

Our Q1 is growth year over year, and we just completed those five years. And we're starting to see that leading edge component of logic accelerate as the gate-all-around nodes are being invested in across the world. Last, as far as the change in administration, it's early. We really can't speculate on what might change there.

So, we'll have to wait for more input on that one.

C.J. Muse -- Analyst

Thank you. Very helpful. As a follow-up, on gross margins, the 48% now is a floor is a pretty good accomplishment. So, would love to hear kind of how you got there and, I guess, how to think about growth beyond that over time.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yeah. I don't think I can be as aggressive to call a floor, but I won't call it peak either. So, 48.4% for Q1, that's mix positive for Q1, but we do expect to continue to make improvements on that 48% baseline. So, we continue to have significant cost projects in our pipeline.

And as we introduce new equipment and improve the value of the equipment that is existing, we'll improve our value pricing. So, we expect to continue to make progress.

C.J. Muse -- Analyst

Thank you.

Operator

Thank you. And our next question comes from the line of Vivek Arya from Bank of America. Your question, please.

Vivek Arya -- Analyst

Thanks for taking my question. On the leading edge, the three big kind of foundries and the IDM among them, one of them is doing extremely well. The other two, not as much. So, when you say that leading edge is very strong, is it -- is the expectation that the one player that is doing very well continues to stay very strong and the others, even if they fall behind, are still sufficient to kind of give the overall industry strong growth outlook for next year? So, I'm just -- I guess the direct question is, how much have you handicapped this kind of dichotomy in the market where one player is doing extremely well and the other two are not doing as well?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Thanks for the question, Vivek. Yeah, the way that we think about forecasting demand long term for the business really starts with the end markets. So, our view, if you think about data center, PC, smartphones, all the things that artificial intelligence that drive the leading edge, we think the eventual footprint of capacity will need to match those end market requirements. And it will be sort of independent of which foundries are serving what amount of each of that demand.

And so, at a high level, we haven't really changed our expectations from the amount of leading-edge capacity that needs to be installed. And so, I would say as customers change their schedules and their micro-factory forecasts, our forecast really hasn't changed.

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Vivek, this is Gary. What I would add is that I've been spending a lot of time with all of these different companies. The really big focus for everybody is improvement in energy-efficient computing. AI is driving a significant amount of growth.

Those die sizes are very large. And so, when we look forward, not just in '25, but we look over longer term, we see significant growth in leading-edge foundry-logic. And the good thing for Applied is that those improvements in energy-efficient computing are really enabled through architecture changes like gate-all-around or backside power distribution, where, in every one of these architecture inflections, you're improving the power efficiency, 20% to 30%. So, it's really, really important.

One of the customers I was talking to said that every percent of energy efficiency improvement matters. And as we've talked about, we're really well positioned to gain share as our customers are going through those inflections with new gate-all-around nodes and backside power. So, that puts -- that gives us a really great tailwind going forward. And as Brice said, we really look at this from an overall market standpoint, and we're pretty optimistic relative to the growth in leading-edge foundry-logic.

Liz Morali -- Vice President, Investor Relations

Thanks, Vivek. We'll take our next question.

Operator

Thank you. And our next question comes from the line of Atif Malik from Citi Group. Your question, please.

Atif Malik -- Analyst

Hi. Thank you for taking my question. I have a question for Brice. Brice, I believe on the last earnings call, you talked about China being 20% offshore sales on a normalized basis next year.

Is that still your view? And some of your peers have talked about a decline anywhere ranging from mid-teens to down 30% for their China sales. And I know you're not talking about WFE next year. But is that kind of the right decline for China sales for you guys as well between 15% and 30%?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Hi, Atif. We have some shaking heads in the room here. We don't recognize -- if I heard you right, we don't recognize the 20%. But I think the last quarter was 32%.

Our quarter -- this quarter reported Q4 is 30% for our China as a share of total revenue. And our outlook quarter Q1 is approximately 30% also. So, we think that's a normalized rate. It was elevated for a few quarters even up into the mid-40s.

And that was because we were shipping that DRAM demand to some specific China customers when it was allowed. Since then, it's come back down to the 30% range. And as we've highlighted in our outlook, that's consistent with our Q1, and we think that's a -- when we look over the past several years, we think 30% is approximately normal for the company. And that does include all of our businesses.

That includes the semi systems, that includes our services business, and our display business, which has significant sales in China.

Atif Malik -- Analyst

Thank you for the clarification.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yep.

Operator

Thank you. And our next question comes from the line of Toshiya Hari from Goldman Sachs. Your question, please.

Toshiya Hari -- Analyst

Hi. Good afternoon. Thank you so much for taking the question. Gary and Brice, I think you both mentioned the concept of value-based pricing a couple of times in your script and how that's driving gross margin.

I know this isn't necessarily a new initiative at Applied, but if you can kind of expand on what you're doing exactly with your customers? Is it primarily tied to your IMS offering, or is it broader than that? And which inning are you in as it pertains to you guys essentially trying to capture value? Thank you.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yeah. Thanks, Toshiya. I would say third inning. And the reason I say that is because -- we are -- since we had the COVID events, we had supply chain and we had changes in our cost, we also had to reconcile with that.

We've always had value pricing in the company. We've always thought about the value of the tools, but that was a bit of a shock in terms of what the cost levels were coming through the supply chain. So, we really had to stimulate our evaluation of the value being provided for each application and especially those integrated applications that are unique to the company. And so, we're in the process of strengthening our training process and our analytical process, and our communications with the customers.

And it's -- since the tools that we're providing and the systems we're providing, we do think create more value for the customers. We're making progress in that.

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Yeah. Toshiya, if I look across all of the different businesses within Applied, I've never been more optimistic regarding the technology pipeline and product pipeline that we have. And our positions around these key inflections that are important for energy-efficient computing. So, as you mentioned, the integrated platforms, that's about 30% of our revenue.

And that's -- those are absolutely crucial for these technology inflections. But I would say that if I look at foundry-logic or DRAM, where we've gained 10 points of share over the last 10 years, or advanced packaging or even in ICAPS, we have new products in the pipeline that will expand our available market and are incredibly valuable for some of these segments. I think we have a really robust pipeline of capabilities, and that will help us from a value pricing standpoint. So, as Brice said, I think we have a lot of room to continue to grow.

Toshiya Hari -- Analyst

Great. Thank you.

Operator

Thank you. And our next question comes from the line of Timothy Arcuri from UBS. Your question, please.

Timothy Arcuri -- Analyst

Thanks a lot. Brice, you gave a number just now. You said that advanced node revenue is going to double. You said it was $2.5 billion, I think, this year.

And you said it's going to double next year. Not all of that's going to be incremental, though, because some is going to cannibalize, I would think N3, N4, N4. So, do you have a sense of how much of that would be incremental? I mean, I'm sure that some of it is, but do you have a sense of how much of it would be?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Thanks, Tim. So, yeah, this approximate doubling has to do with our shipments to the gate-all-around nodes across the industry. And what we've said is in the fiscal '24, we shipped approximately $2.5 billion of equipment to gate-all-around nodes, and we expect that to approximately double next year. And if I think about it, we've also described the increment for gate-all-around for us is approximately $1 billion, raising what was a $6 billion investment for 100,000 wafer starts of capacity, wafer starts per month to $7 billion.

So, the increment would be about one-sixth if you're thinking about it from that perspective. And then I think most of our shipments at this point are the -- in the leading-edge logic are toward gate-all-around nodes. So, most of that is replacing revenue that was at prior nodes in the past.

Timothy Arcuri -- Analyst

Very, very helpful. Thank you. And then, Gary, I know you talked about $1 trillion in semiconductor revenue that's this much-ballyhooed longer-term number. But my question is, how much WFE spending do you think has to be spent to support that much revenue? And really, it kind of gets to what the longer-term WFE intensity is, which used to be 13.5% before COVID and it got to like 17% in 2023, but it's been coming down since then as China has come down.

So, how do you think about like for $1 trillion worth of semiconductor revenue? How much WFE do you think the industry has to spend to support that? I don't know, Brice, if you want to answer that or Gary.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Thank you. Yeah, I can jump in on that because we have seen elevated intensity this -- the WFE investment, the equipment investment over semiconductor revenues. So, we've seen that intensity increase, largely on that significant ramp in China over the past couple of years as China ramped up capacity. So, we do expect it to decrease a little bit over time as we look forward in the forecast.

But we're comfortable at this point that it should stay in the mid-teens, somewhere in the mid-teens as a metric.

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Yeah. Tim, the other thing I would add is that we're very deeply engaged with all of our customers. I would say more so than ever, this concept of high-velocity co-innovation where we're co-innovating with our customers a decade out over multiple technology nodes has never been stronger with all of our innovative technologies, our device integration teams, really deep partnerships with customers. And what we see going forward besides overall capital intensity is increasing intensity in materials engineering and the technologies from Applied Materials.

So, I think, again, we have very, very deep visibility across all of these different market segments, and that will put us in a good position.

Timothy Arcuri -- Analyst

Thank you both.

Operator

Thank you. And our next question comes from the line of Krish Sankar from TD Cowen. Your question, please.

Krish Sankar -- Analyst

Yeah. Hi. Thanks for taking my question. Gary or Brice, I just wanted to follow up again on the value-based pricing argument.

Is part of it driven by some of these technologies like gate-all-around where it's really difficult to do some of the vertical steps and therefore, there's a lot more value added to it? The reason I'm asking is, once we get past gate-all-around, go to backside power delivery or even 6F squared DRAM, does that intensity come down? In other words, gate-all-around so difficult to do, the next steps might not be as critical. I'm just kind of curious to think -- how to think about this value pricing and whether it was a gate-all-around-specific thing.

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Hi, Krish. This is Gary. Thanks for the question. So, I would say that the entire industry is focused on energy-efficient computing.

And we've heard some of the system companies talking about 100x improvements in five years or 10,000 times improvements in 15 years. It's really hard to accomplish those types of improvements. And the value, why do these companies go to the most advanced nodes? They go there, even though those wafers are more expensive because one CEO was telling me even 1% improvement in energy-efficient computing is worth a lot. So, when you think about all of these different nodes, yes, gate-all-around is difficult.

Backside power is difficult. 4F squared and 3D DRAM are difficult. All of these areas are very, very challenging. And we have unique capability with our integrated platforms.

We have one platform with multiple technologies that enables a 50% improvement in resistance. And obviously, that's really critical for energy-efficient computing. So, I don't think this is a one-shot thing with the first generation of gate-all-around. All of these things, I think, are critical for customers, and Applied is extremely well-positioned.

Krish Sankar -- Analyst

Thanks, Gary. Very helpful.

Thank you. And our next question comes from the line of Harlan Sur from JPMorgan. Your question, please.

Harlan Sur -- Analyst

Yeah. Good afternoon. Thanks for taking my question. On the team's services business, strong performance -- sorry, '21 consecutive quarters of year-over-year growth, and that trend clearly looks to sustain going into an improving semiconductor demand environment next year.

Additionally, you guys have driven a much more annuity-like recurring and attractive revenue profile. However, operating margins are still about 100 basis points, below the 31% level that you drove for five, six consecutive quarters in fiscal '21 and '22 time frame and that was at a lower revenue base. And then maybe about 200, 300 basis points below your prior long-term targets for low 30s percent operating profitability and revenue targets that were also lower. So, what's been responsible for the lower operating margin expansion? Is there still line of sight to getting into the low 30% range on continued AGS growth? Or is there something sort of structurally that has changed?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yeah. Harlan, thanks for the question. There is something structurally that's changed. We have begun allocating more of our corporate expenses and our central expenses that are supporting each of our segments during this year, and that was accountable for a portion of the reduction in operating profit there.

So, I think you see us improving our operating profit for that business over the last eight quarters generally. And I think the expectation is we'll continue to be able to make improvements even with those allocations that allocation increase that we made.

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Yeah. Harlan, you also -- there's tremendous pull as customers are going through these inflections in all of these different markets to accelerate time to market for those innovations and then transferring technology, first time right, faster technology transfer and then ramp into high-volume manufacturing, those are big opportunities. We're also driving tremendous innovation in our services. And I've been meeting with a lot of the different customers here over the next quarter, there's real traction for many of these service innovations.

So, that will continue to drive the value we create for our customers and drive our margins higher in the future.

Harlan Sur -- Analyst

I appreciate that. And maybe just a quick follow-up. So, as you guys focus on more value capture, especially with your integrated solutions. Gary, you spent a lot of time talking about sort of new technology enablement with these integrated systems.

Do your customers also get the additional benefit in terms of better operational and manufacturability dynamics? I mean, I can imagine with an integrated system, you eliminate a lot of the wafer transport -- transfer activities, which ultimately increases process module throughput, increase in cycle time. You also potentially get smaller tool footprint, right? Is this an accurate assessment and any way to kind of quantify some of these operational benefits with your integrated systems?

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Yeah. Thanks for the question. So, we're always focused on improvements in energy-efficient computing and all of these different architectures, but there is also a huge focus in cost innovation. And cost innovation when we're combining these different technologies together is one aspect, but the other thing is really helping our customers optimize this new device architecture.

So, when we're in these technology discussions with a number of different companies, there are cases where we can simplify processes that really enable them to drive lower costs. Another example is with our pattern-shaping technology that we've talked about, where our customers can reduce the number of EUV steps. So, there are a number of those kinds of opportunities. And then getting back to services, again, I was with one of our biggest customers here recently, and we were talking about service innovation that can drive their overall operating costs lower.

So, there are -- this is also a really big focus, and I think an opportunity both for our systems business and our service business.

Harlan Sur -- Analyst

Thank you, Gary.

Operator

Thank you. And our next question comes from the line of Joe Quatrochi from Wells Fargo. Your question, please.

Joe Quatrochi -- Wells Fargo Securities -- Analyst

Hey, thanks for taking the question. You mentioned in the prepared remarks that you were seeing DRAM customers accelerate capacity plans, especially for HBM. I think most people expect HBM to continue to be strong spending. But are you seeing customers look to add capacity for conventional DRAM? I just want to make sure I understand that comment right.

And then how do we think about just the growth that you talked about sequentially from memory into the January quarter?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Hi, Joe. We do see customers adding capacity in DRAM in total, more wafer start capacity. I actually haven't calculated how much of that was driven by HBM. What we would say is about 10% of DRAM wafers right now are allocated toward HBM production, high-bandwidth memory.

And the high-bandwidth memory demand is growing at about a 30% rate. So, we do see more capacity allocated each quarter to high-bandwidth memory, and we do see the growth rate there very high. My sense is that doesn't equate to exactly what's being added in the overall capacity footprint. But anyway, we do see capacity increases in the DRAM customers.

And we do see that market continue to be fairly strong.

Operator

Thank you. And our next question comes from the line of Srini Pajjuri from Raymond James. Your question, please.

Srini Pajjuri -- Analyst

Thank you. I have a follow-up to the previous question, Brice. If I look at your DRAM, obviously, very strong in fiscal '24. I think you said 60-plus percent growth.

And you kind of quantified the HBM at $700 million roughly. I think that's roughly about 20 points of growth. So, as I look out to the next, I guess, fiscal year, I'm just trying to understand how to think about overall DRAM growth because HBM will obviously grow. And I believe there is some China in the last 12 months, that's probably declining or already declined.

So, all in, do you expect, I guess, DRAM to grow next year? Or do you think it's going to be a challenge? Thank you.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yeah. So, a couple of comments there. Long term, we've talked about the $1 trillion market. And our view that -- $1 trillion semiconductor market in our view that capacity will be continued to be added across the ecosystem on the wafer side to support that.

I think we've articulated in the past that for WFE, we expect about two-thirds to be foundry-logic and one-third to be memory. We haven't gotten specific about what the share is for DRAM. But right now, today, in our Q4 and our Q1 guide, we're seeing a strong DRAM market, and that's a continuation. And we talked about the pull of high-bandwidth memory from the artificial intelligence usage models.

So, I think it's fair that we expect capacity to be added over time, and we're not making a call on '25, but those are the dynamics.

Srini Pajjuri -- Analyst

Got it. And then maybe another quick one on NAND. I know you guys have been fairly cautious on WFE spending when it comes to NAND. But there is definitely some optimism about tech transitions and in particular, in molyb transition.

So, just want to hear your thoughts about how you're thinking about NAND for next year in terms of tech transitions and the opportunity for you guys.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yeah. From a macro perspective, similar to the comments on DRAM, we do see a little bit of growth in NAND in our Q1 outlook. And the dynamic is slightly different at the macro level for NAND and DRAM. On the DRAM side, we do see added capacity, more wafer starts across the ecosystem.

On the NAND, we haven't seen that because I think the bit rate density, so the actual shrink rate of the NAND technologies has been so impressive and so high that it's actually delivered the amount of bits that are in the demand profile. And so, there hasn't been new wafer starts needed on the NAND side. So, most of that has been an upgrade market, so that dynamic is slightly different. But in any case, we see a little bit of an uptick in the NAND in our outlook for Q1.

Srini Pajjuri -- Analyst

Thank you.

Operator

Thank you. And our next question comes from the line of Brian Chin from Stifel. Your question, please.

Brian Chin -- Analyst

Hi there. I appreciate the time this afternoon. It sounds like you still view 30% as a normalized level of China sales, but of course, it did go higher than normalized into the 40s in recent quarters. So, I was curious, is it reasonable that China could go below 30% in '25 if areas like leading-edge foundry or DRAM improve and ICAPS remains more stable, plus or minus?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Thanks for the question, Brian. I think that most of the variability for us will be based on the health of the ICAPS market in China. That's the vast majority of our business right now. We have served most of the DRAM and NAND business that we can serve, and we can't serve leading edge in China.

So, the vast majority of the business is ICAPS, and it will just depend on how that ICAPS market evolves. Earlier, I shared that there's a couple of signals that say the rate of investment might be slower. Those are higher inventory positions and slow end markets that are automotive, industrial, image sensors and analog are markets that are slower. But having said that, our Q4 and Q1 outlook is still strong for ICAPS across the world, and so we'll just have to see how that matures.

We do expect customers to continue to add capacity over the medium term.

Brian Chin -- Analyst

All right. Thank you. Maybe if I could just ask a little bit of a longer-term question here. ASML earlier today was upbeat on its outlook for AI-driven DRAM spending overall.

They also talked about lithography intensity increasing for DRAM toward decade end. This seems to differ, I guess, a little bit from your prior messaging around the potential timing and introduction of technologies like vertical transistor DRAM and even 3D DRAM. Can you maybe compare and contrast where the differences here might arise?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

I'll say one thing, and then Gary will help here. I think my view is it's complementary, very complementary. So, as there's more business and more demand on the litho side of the equation, that, of course, requires more equipment to do the actual materials. Gary has a comment.

Gary E. Dickerson -- President, Chief Executive Officer, and Director

Yeah. We're deeply engaged with all of the memory companies on their DRAM road maps. So, relative to the vertical channel transistor, also known as 4F-squared, I think that's where everybody is focused in the near term. We believe that inflection will be more materials engineering-intensive.

And again, we're really deeply engaged on the key technologies that will enable that architecture inflection. And I would say that everyone is also focused on 3D DRAM, and that one is further out in time, and that is significantly more materials engineering-intensive. So, again, I can't really comment on what other people are seeing, but I would say that we're deeply engaged with all of those different companies. On those architectures, we're working with their integration teams, their device teams, and we have high confidence that materials engineering intensity will increase with those inflections.

Brian Chin -- Analyst

All right. Thank you.

Operator

Thank you. And our next question comes from the line of Joseph Moore from Morgan Stanley. Your question, please.

Joseph Moore -- Analyst

Great. Thank you. I wanted to follow up the strength in ICAPS. You sort of said there's weakness in automotive, industrial, analog, and image sensors.

That's a lot of the trailing edge category. So, I'm wondering what does that leave that's doing well? And does that sort of imply that it's geopolitically related spending? Is there -- just what aspect of it is it that's still strong?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Yeah. Thanks, Joe. I think power -- some of the power-related components and I think some of the microcontrollers are stronger than those markets. Those are two that I recall from the discussions.

So, I think what we see across ICAPS is it's continued to be fairly strong. It wasn't quite as high in our Q4 '24 as in our Q4 '23, but still a very strong market. So, we'll just have to watch how this evolves. Our perspective is that customers will continue to add capacity as the underlying market continues to grow toward this trillion-dollar 2030 semiconductor market.

But utilizations right now are a little bit lower than the ideal utilization level, so we do think there could be some slowing of investment as we go through this year.

Liz Morali -- Vice President, Investor Relations

Thanks, Joe. We have time for one last question.

Operator

Certainly. And our final question for today then comes from the line of Vijay Rakesh from Mizuho. Your question, please.

Vijay Rakesh -- Analyst

Yeah. Hi. Just a quick question. On the China side, Gary and Brice, when you look at the China revenues, do you expect it to kind of hold at these levels going through calendar '25?

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services

Thanks, Vijay. In our Q1 guide, we are highlighting that it is also approximately 30%, and looking historically, that's been the number that we've seen historically. And I'll just say that the market for us, I highlighted a few minutes ago, we're not serving much DRAM or NAND and no leading edge at this point. It's mostly the ICAPS business.

And so, the fact that it's been restricted to the ICAPS business at this point, it will really change over time with the strength of that particular end market. We do expect that to grow over time. We'll have to see how '25 shakes out as the market matures.

Vijay Rakesh -- Analyst

Thanks for the question.

Operator

Thank you. This does conclude the question-and-answer session of today's program. I'd like to hand the program back to Brice for any further remarks.

Brice Hill -- Senior Vice President, Chief Financial Officer and Global Information Services
