China’s CXMT is preparing to expand into NAND flash memory as artificial intelligence data centres drive stronger demand for storage chips. The move could put the DRAM specialist into direct competition with Samsung, SK Hynix, Micron and China’s YMTC amid a global memory supply squeeze.
CXMT Prepares NAND Flash Expansion in China
Chinese memory chipmaker ChangXin Memory Technologies, known as CXMT, is preparing to enter the NAND flash memory market, according to people familiar with the company’s plans. Reuters reported on September 18 that CXMT plans to establish a research and development production line for NAND chips at its new facility in Beijing.
The move would represent a significant expansion beyond CXMT’s established DRAM business. NAND and DRAM are both forms of semiconductor memory, but they serve different purposes across computing devices.
CXMT has also established a research institute in Beijing, with projects including NAND development. The company has begun discussions with potential customers, including an AI-focused startup, according to Reuters.
The planned expansion comes as memory manufacturers worldwide are dealing with strong demand from artificial intelligence infrastructure. Industry executives expect tight memory supply to continue through at least 2027, while TrendForce expects NAND supply tightness to ease only in the second half of next year.
AI Servers Are Driving Memory Demand
Artificial intelligence is changing the balance of demand across the semiconductor industry.
AI data centres require large amounts of computing memory and storage to support servers handling increasingly complex workloads. The expansion of AI infrastructure has therefore increased demand for both high-performance memory and enterprise storage products.
This has contributed to a broader memory supply squeeze. SK Hynix CEO Kwak Noh-jung said in July that 2027 could become the industry’s most difficult year from a supply perspective, according to Reuters.
NAND flash memory is particularly important for solid-state drives, enterprise storage and other products where large quantities of data need to be stored and accessed quickly.
As AI companies build larger data centres, demand for enterprise storage is also increasing. That creates an opportunity for memory manufacturers capable of producing NAND at competitive prices and meeting the technical requirements of major customers.
CXMT’s decision to explore NAND therefore comes at a time when the market is facing both strong demand and limited supply growth.
CXMT Would Challenge Samsung and Other Leaders
The NAND market is dominated by established global manufacturers, including Samsung Electronics, SK Hynix, Micron and Japan’s Kioxia. China already has a major NAND producer in Yangtze Memory Technologies Corporation, or YMTC.
CXMT’s entry would consequently create a new competitive dynamic within China’s semiconductor industry.
CXMT currently has a strong focus on DRAM, which is widely used in computers, smartphones and servers. NAND would give the company exposure to a separate memory segment with different technologies, customers and manufacturing requirements.
The expansion could also allow CXMT to broaden its customer base at a time when memory prices and demand are being influenced heavily by AI infrastructure.
However, establishing an R&D production line is not the same as reaching large-scale commercial production. CXMT would still need to demonstrate that its NAND technology can achieve the performance, reliability, manufacturing yields and cost structure required by customers.
That distinction will be important as the company moves from research towards potential commercial production.
YMTC Faces a New Domestic Competitor
CXMT’s planned NAND expansion could also change competition within China’s semiconductor industry.
YMTC has traditionally been China’s major player in NAND flash memory, while CXMT has concentrated on DRAM. The two companies have therefore operated largely in different areas of the memory market.
CXMT’s move would bring the companies into more direct competition.
The timing is significant because China’s semiconductor industry is receiving substantial government and local-government support as Beijing seeks to strengthen domestic chip manufacturing. Reuters reported that both CXMT and YMTC are central to China’s effort to build a more self-reliant semiconductor industry.
CXMT has also raised substantial capital. Reuters reported that the company raised $8.6 billion through a 2026 IPO, while YMTC’s parent company is preparing for a potential Shanghai listing.
The additional capital available to China’s memory companies could support investment in new facilities, research and manufacturing capacity.
Global Memory Shortage Keeps Pressure High
The immediate backdrop to CXMT’s NAND plans is a global memory shortage.
Memory manufacturers are facing increased demand at a time when expanding production capacity takes years and requires significant capital expenditure.
The semiconductor industry is also dealing with competing demands for manufacturing capacity. AI-related products can command significant production resources, while conventional electronics, smartphones, PCs and enterprise storage continue to require memory.
Reuters reported that industry executives expect the global memory shortage to persist through at least 2027. TrendForce has separately projected that NAND supply tightness may not ease until the second half of 2027.
This creates an unusual situation for the memory industry. Manufacturers are investing in additional capacity while customers are simultaneously trying to secure future supply.
For buyers, that can mean longer-term supply agreements and increased competition for available production.
NAND Has Become Critical for AI Infrastructure
NAND flash is not the same type of memory as the high-bandwidth memory used directly alongside AI accelerators, but the two markets are increasingly connected through data-centre expansion.
AI systems generate and process enormous quantities of information. Data centres therefore need storage systems capable of holding training datasets, model files, application data and other information.
Enterprise solid-state drives use NAND flash to provide high-capacity storage with faster access than traditional hard drives.
As AI infrastructure expands, storage demand can grow alongside computing capacity.
That has increased the strategic importance of NAND manufacturers. Companies that can expand supply while maintaining competitive pricing may gain greater access to customers building new data-centre capacity.
CXMT’s planned entry therefore comes at a time when NAND is becoming increasingly important within the broader AI infrastructure supply chain.
China’s Semiconductor Push Adds Strategic Importance
CXMT’s expansion also fits into China’s wider effort to strengthen domestic semiconductor manufacturing.
US export restrictions have limited Chinese companies’ access to some advanced semiconductor technologies and equipment. That has increased pressure on Chinese manufacturers to develop domestic alternatives and build more resilient supply chains.
Memory has become a particularly important part of that effort because China remains a major producer and consumer of electronics.
CXMT has already been expanding its DRAM business, while YMTC has focused on NAND. Their progress gives China domestic capabilities in two major memory categories.
Adding another NAND producer could increase the country’s manufacturing capacity and reduce reliance on foreign suppliers over time.
The commercial outcome, however, will depend on technology, manufacturing scale and customer acceptance. Government backing can provide capital and strategic support, but memory production remains a technically demanding and highly cyclical business.
CXMT’s Smartphone Progress Shows Its Expansion
CXMT’s growth in DRAM also provides context for its decision to enter NAND.
Recent reports indicate that Chinese smartphone manufacturers are increasingly using CXMT memory in flagship devices. South China Morning Post reported that ZTE-backed Nubia’s NaviX Ultra uses CXMT’s LPDDR5X DRAM, while the company described the partnership as the first large-scale use of domestically produced LPDDR5X at that level.
That development shows how China’s domestic memory suppliers are moving beyond lower-end applications.
For CXMT, establishing relationships with major device manufacturers could provide an important customer base as the company expands its product portfolio.
NAND would open another route into consumer electronics and data-centre storage.
But NAND manufacturing involves different production processes and technical requirements. CXMT will need to establish its capabilities independently rather than relying on its DRAM progress as proof of NAND competitiveness.
Memory Prices and Supply Will Stay Under Watch
The memory shortage has already changed the economics of the semiconductor sector.
When supply is tight, manufacturers can gain pricing power, while electronics companies face higher component costs and greater pressure to secure supply.
For smartphone and PC manufacturers, memory prices can influence the cost of producing devices. For cloud providers and AI companies, storage and server memory are part of the capital cost of building data centres.
This creates strong incentives for buyers to lock in supply.
CXMT’s planned NAND expansion could eventually increase competition and provide another source of supply, particularly for Chinese customers. But that impact would take time because the company is currently preparing an R&D production line rather than announcing immediate mass-market NAND production.
The global market will therefore continue to depend primarily on existing manufacturers while new capacity is developed.
What CXMT’s NAND Move Means for the Market
CXMT’s planned entry into NAND comes at the intersection of three major trends: rising AI infrastructure demand, tight global memory supply and China’s push for greater semiconductor self-reliance.
The company would face established competitors with decades of NAND manufacturing experience. At the same time, the current shortage creates a strong commercial incentive for customers to consider additional suppliers.
The most immediate significance is strategic rather than a sudden change in global NAND supply.
If CXMT successfully develops competitive NAND technology and eventually scales production, it could alter China’s memory industry and add another significant Chinese producer to the global market.
For now, investors and semiconductor customers will be watching CXMT’s Beijing R&D line, its customer discussions and the pace at which the company converts its DRAM expertise into NAND capabilities.
The broader memory shortage is unlikely to disappear quickly. That gives CXMT a window to invest while demand remains strong, but it also places pressure on the company to execute in a market dominated by highly experienced competitors.
