ChangXin Memory Technologies (CXMT), China's dominant domestic memory chip producer, is in preliminary discussions with authorities in Beijing's Yizhuang Economic and Technological Development Zone to build a new 12-inch DRAM wafer fabrication plant, Reuters reported. The proposed facility — which would sit adjacent to the company's existing Beijing factory — comes on top of expansions already under construction in Shanghai and Hefei that alone are expected to push CXMT's monthly output past 600,000 wafers, more than doubling current capacity. The new Beijing fab, if approved, would add further to that figure.
Yizhuang zone authorities have been approached about providing at least 60 million yuan in support funding, with other state-backed technology companies also expressing interest in taking equity stakes, according to the Reuters report. Negotiations remain at an early stage, and the final size and structure of any deal could change.
CXMT currently operates two 12-inch DRAM fabs in Hefei, the Anhui provincial capital, and one in Beijing, each with a monthly capacity of roughly 100,000 wafers. The company completed an $8.6 billion initial public offering in July — the largest in China's semiconductor industry history — with shares surging 466% on their debut day. The stock has continued to climb since.
Beijing Adopts Hefei's State-Backed DRAM Playbook
CXMT's rise has become the benchmark for a broader Chinese industrial policy template. In Hefei, state investment funds, preferential land grants, and direct government subsidies — a package commonly called the "Hefei Model" — were instrumental in building what is now China's only commercial-scale DRAM producer. That template is now being systematically replicated in other cities.
Beijing's approach fits the pattern closely. The Yizhuang zone has previously funded CXMT's existing Beijing plant through its investment affiliate, Yizhuang Capital. The zone also hosts SMIC, NAURA Technology Group, and Xiaomi, and has in recent years pushed aggressively into robotics and embodied AI research — it hosted the world's first humanoid robot half-marathon in April 2025.
The 60 million yuan figure under discussion is far below the more than $1 billion typically required to build and equip an advanced DRAM facility. That gap indicates local government money is designed to function as a catalyst — anchoring CXMT's commitment to the site while larger contributions come from the company itself and other state-owned investors.
Beijing and Shanghai are now openly competing for CXMT production capacity, with both cities treating domestic memory manufacturing as both an economic prize and a national security imperative. For local governments across China, hosting a CXMT facility has become as much a political performance indicator as an industrial one.
CXMT Wins Domestic Pricing Power but Trails Global Leaders
Despite its rapid expansion, CXMT remains well behind the three dominant global players. Samsung Electronics, SK Hynix, and Micron Technology together control close to 90% of worldwide DRAM market share, and all three maintain significant advantages in manufacturing technology and yield rates. The gap is most pronounced in advanced high-bandwidth memory used in AI accelerators.
Where CXMT has made tangible progress is in China's domestic market. The company secured a reported $3 billion DRAM supply deal with Tencent, and has established pricing leverage with Chinese cloud and technology buyers more broadly. Under sustained US export controls restricting Chinese companies' access to the most advanced foreign chips and equipment, CXMT's mature-node DRAM has found a captive and growing customer base.
The company's apparent strategy is sequenced: build manufacturing scale and domestic market dominance first in conventional DRAM, then progressively close the technology gap in more advanced memory generations. China's continued investment in mature-process capacity, even as Washington tightens restrictions on advanced semiconductor equipment, reflects that deliberate pacing.
China's DRAM Buildup Reshapes AI Supply Chain Calculus
The broader significance of CXMT's expansion extends beyond any single company's production schedule. AI data centers require DRAM at scale, and memory is increasingly treated as a strategic resource on par with GPUs. The race to secure domestic supply has accelerated sharply on both sides of the US-China technology divide.
Should CXMT's Beijing, Shanghai, and additional Hefei plants all come online as planned, China's domestic memory output would reach a level capable of influencing global DRAM pricing and reconfiguring supply chains that have long run through South Korea and the United States.
For Taiwan, the implications are direct. Memory chips are a critical bottleneck in AI and high-performance computing, and China's methodical capacity build-out represents another step in Beijing's effort to reduce dependence on non-Chinese supply chains. CXMT's current technology nodes and yield rates still fall short of international frontrunners, but the pace of its state-backed industrial ramp-up makes the trajectory difficult to dismiss.
Yizhuang's significance, in this context, may extend beyond the fab itself. With CXMT's memory manufacturing on one side, JD.com's logistics and cloud infrastructure operations nearby, and a dense cluster of semiconductor equipment makers and AI firms in between, Beijing is assembling something more ambitious than a production hub — an integrated technology ecosystem linking silicon fabrication to AI application, bound together by state capital and industrial policy.
