Yangtze Memory Technologies (YMTC) is one of the clearest examples of China using concentrated industrial investment to enter a semiconductor market dominated by established Korean, Japanese and U.S. suppliers. Founded in Wuhan in 2016, the company began with no domestic mass production of NAND flash. By the second quarter of 2026, Counterpoint Research data placed it among the world’s top three suppliers by NAND bit shipments, with a 14% share. 34
That progress does not mean YMTC has overtaken the market leaders. It means a late entrant has moved from technological and manufacturing dependence to meaningful global scale in roughly a decade—and is now seeking another large pool of capital to keep advancing.
A state-backed project built around NAND independence
YMTC was established in July 2016 by Tsinghua Unigroup, the National Integrated Circuit Industry Investment Fund, the Hubei Integrated Circuit Industry Investment Fund and the Hubei Science & Technology Investment Group. A study of China’s integrated-circuit industry puts the company’s total investment at about RMB 160 billion. The National Memory Base, with YMTC as its principal enterprise, began construction in Wuhan later that year. 18
The starting point was a strategic deficit. China did not yet have domestic mass production of NAND flash, while overseas suppliers were already developing more advanced 3D NAND technologies. YMTC therefore had to build several capabilities at once: chip design, process development, fab operations, customer qualification and a supply chain capable of supporting high-volume memory production.
That combination made the project much more than a conventional startup. NAND manufacturing requires enormous and sustained capital spending, while the product itself is highly cyclical. A company must continue developing new generations even when prices fall and margins disappear.
YMTC’s technology catch-up was fast—but not linear
YMTC’s own milestone record shows how quickly it moved from design to manufacturing. It completed its first-generation 3D NAND test-chip design in 2016, achieved first silicon for a 32-layer device in 2017 and began mass production of that generation in 2018. 19
The company then advanced through several generations:
- 32-layer 3D NAND: first silicon in 2017 and mass production in 2018.
19
- 64-layer NAND: YMTC announced the technology in 2018 and reached full production by 2020, according to TechInsights.
17
- 128-layer QLC NAND: YMTC announced a 128-layer, 1.33-terabit QLC device in 2020 after skipping a conventional commercial 96-layer generation.
- 232-layer NAND: the company subsequently brought a 232-layer product to market, marking another major step in vertical scaling.
- 294-layer NAND: industry reporting identified a 294-layer generation by 2025.
15
A central part of this strategy was YMTC’s Xtacking architecture. The approach separates the memory-cell array from the peripheral circuitry and then connects the two, an arrangement intended to accelerate development and improve the trade-offs among performance, density and manufacturing cost. Xtacking was unveiled publicly in 2018, when it also received a Flash Memory Summit award. 19
The significance of this progression is not that layer count alone proves parity with every rival. Modern NAND competitiveness also depends on yields, reliability, die economics, controllers, firmware, enterprise qualification and the ability to manufacture consistently at scale. Layer counts are useful markers of process ambition, but they are not a complete measure of commercial leadership.
Scale turned technical progress into market share
YMTC’s expansion was supported by continued spending on fabs, equipment and process improvements, even through a difficult NAND cycle. The company’s prospectus-related reporting describes substantial cumulative investment in long-term assets and research and development, while separate reporting says YMTC recorded a full-year loss during the 2023 NAND downturn. 49
That willingness to keep investing matters because memory markets often punish suppliers that expand at the wrong time. YMTC instead used the downturn to pursue manufacturing scale and customer adoption. Aggressive pricing can help a new supplier fill fabs, build shipment volume and gain qualification with domestic device makers and storage companies. It can also make a local alternative more difficult for customers to ignore.
The strategy carried a cost. YMTC reportedly became profitable only in 2024, illustrating how long it took for the company’s scale and pricing power to overcome the burden of building a major memory operation. 2

What the 14% figure actually means
Counterpoint Research’s second-quarter 2026 data put Samsung at 25% of global NAND bit shipments, the combined SK hynix/Solidigm group at 22% and YMTC at 14%. That placed YMTC third in the ranking, narrowly ahead of Kioxia on the reported measure. 34
The wording matters: 14% is a share of NAND bits shipped, not necessarily a share of installed fab capacity, industry revenue or profit. NAND products vary in density, price, customer mix and qualification status. A supplier can therefore rank strongly by bits while still trailing larger rivals in revenue or high-end enterprise capability.
Separate disclosures from YMTC’s IPO process said the company ranked third globally in both sales value and shipment volume during January–March 2026, although those rankings were based on company prospectus calculations. 5 Taken together, the figures show that YMTC’s rise is commercially significant, while still leaving room for caution about how closely it matches the leaders across the full market.
Why the accepted STAR Market application matters
The Shanghai Stock Exchange accepted the listing application of YMTC’s parent, CCSH, for the STAR Market in August 2026. That is an important procedural milestone, but it does not mean the IPO has been completed or that final listing approval has been granted. 1
The proposed offering would raise about RMB 33 billion. Reporting on the plan says roughly RMB 20.8 billion would go toward upgrading mass-production lines, while RMB 12.2 billion would support advanced technology research and other projects. 2

The proposed use of proceeds reveals the company’s immediate priorities. YMTC is not simply seeking money to build a larger corporate balance sheet. It is targeting the operational bottlenecks that determine whether advanced NAND becomes a competitive product: process optimization, yield improvement, production capacity and the next generation of memory and storage technologies.
The listing would also deepen the role of China’s domestic capital markets in semiconductor development. YMTC’s growth began with state-backed industrial funding; a STAR Market offering could add public-market capital to that model and help finance the long development cycles required by advanced NAND.
Has YMTC broken the NAND oligopoly?
Not yet. YMTC has become a consequential fourth source of global supply, but Samsung and the SK hynix/Solidigm group still held substantially larger shipment shares in Counterpoint’s Q2 2026 data. 34
Its impact is nevertheless real. A stronger YMTC can:
- give Chinese electronics and storage companies another source of NAND;
- reduce China’s dependence on foreign memory suppliers;
- put additional pressure on pricing and customer negotiations; and
- force established vendors to account for a competitor willing to invest through downturns.
The company’s progress also changes the strategic question. The issue is no longer whether China can create a NAND manufacturer from scratch. YMTC has demonstrated that it can reach global top-three shipment status. The harder question is whether it can sustain that position while improving yields, qualifying products for demanding enterprise customers, expanding capacity and managing equipment and supply-chain constraints.
The next test is durability, not another headline layer count
YMTC’s rise rests on three mutually reinforcing pillars: large-scale industrial backing, rapid process iteration and a willingness to spend for manufacturing scale. Its accepted IPO application suggests that this effort is entering a more commercially accountable phase, with domestic investors potentially helping fund the next stage.
But NAND remains cyclical, and the competitive frontier continues to move. Reporting cited by Pandaily placed YMTC at 294 layers by 2025, while the wider industry began shipping 300-plus-layer devices in 2026 and was looking toward roughly 400 layers. 15 YMTC must therefore keep advancing while proving that its products can deliver consistent economics and reliability at volume.
The most accurate verdict is measured: YMTC has made China’s challenge to the NAND oligopoly industrially credible and durable, but it has not yet displaced the established leaders. Its IPO could provide important fuel for closing that gap; it cannot by itself guarantee that the gap will disappear.
