CXMT Plans to Enter Flash Memory Market, Set to Compete Directly with Samsung and YMTC
nashnova research
China's DRAM champion CXMT is preparing to enter the NAND flash market, with an R&D line planned in Beijing. This means the boundary between China's two memory-chip giants is vanishing — a direct DRAM-vs-NAND crossover battle is taking shape.
What is CXMT planning?
Three people familiar with the matter told Reuters that CXMT plans to build a NAND R&D production line at a new Beijing facility and has set up a research institute there.
The company has already discussed its NAND plans with customers, including a startup that intends to use the chips in AI-system and supercomputer storage products.
It remains unclear when the R&D line will be operational — or whether CXMT will push from pilot production to full-scale commercial manufacturing.
Why move into NAND now?
Surging AI-server demand has triggered a global memory-chip shortage; industry executives expect tight supply at least through 2027.
This means → the market has opened a window: demand keeps climbing, but leading manufacturers are funneling capex into DRAM and HBM — high-bandwidth memory, the ultra-fast chips paired with AI accelerators — leaving NAND capacity expansion squeezed.
In plain terms = the majors are chasing higher-margin AI memory, so flash is the segment where nobody is adding capacity — and that lowers the barrier for a new entrant.
What does the "twin stars" territory swap signal?
CXMT and YMTC previously stayed in separate lanes: CXMT in DRAM, YMTC in NAND. Now both are pushing into each other's domain — Reuters reported in April that YMTC had sent low-power DRAM samples to customers.
This means → China's memory industry is shifting from "complementary division of labor" to "full-spectrum competition," with the two firms potentially fighting over the same customers and the same product designs.
This reflects a deeper dynamic: under U.S. export controls, Chinese memory firms are moving to cover every category they can, rather than defend a single niche.
Where is the money coming from?
CXMT completed a 57.92 billion yuan (≈$8.6 billion) IPO in July — the largest in Asia this year.
Reuters reported last month that CXMT plans to build a second memory-chip fab in Beijing and is in financing talks with a government-backed tech-manufacturing park.
YMTC's parent, CCSH, is also preparing a Shanghai listing targeting 33 billion yuan — both companies are raising capital aggressively to fund expansion.
Who are the rivals, and how big is the gap?
Global NAND landscape: Samsung Electronics leads with a 29.3% revenue market share, followed by SK Hynix and Micron (TrendForce data).
YMTC is China's domestic NAND leader, but was placed on the U.S. Entity List in 2022, restricting its access to advanced equipment.
In plain terms = CXMT faces two hurdles at once — closing the technology gap with the global big three and competing head-on with YMTC at home.
What will determine whether this works?
The core question: whether the R&D line can advance from pilot to mass production — that is the make-or-break point for the crossover strategy.
Both "twin stars" receive funding from the National IC Industry Investment Fund and local governments — CXMT backed by Hefei, YMTC by Wuhan — reflecting intense competition among Chinese provinces to attract strategic industries.
This means → capital is not the biggest bottleneck; the real test is technology accumulation and customer qualification — NAND process technology diverges significantly from DRAM, and money alone cannot shortcut that learning curve.
