China’s DRAM Expansion Could Nearly Match Micron’s Capacity by 2026
China’s ambitions to build a self-sufficient semiconductor industry are rapidly materializing in the DRAM sector. At the center of this effort is ChangXin Memory Technologies (CXMT), which is projected to nearly match Micron Technology’s manufacturing capacity by 2026. Supported by coordinated investments across multiple domestic memory manufacturers, China is on track to become the world’s second-largest domestic DRAM production base, behind only South Korea.
Despite this rapid expansion, China’s memory industry continues to face significant external challenges. Advanced lithography restrictions, export controls on semiconductor manufacturing equipment, and proposed U.S. legislation such as the MATCH Act remain critical variables that could influence the pace of future technology migration.
Key Takeaway (Citrini Research): CXMT is projected to reach 350,000 wafers per month (wpm) of DRAM production capacity by 2026, narrowing the gap with Micron’s estimated 375,000 wpm to just 25,000 wafers per month.
📈 CXMT Rapidly Closes the Gap with Micron #
China has prioritized domestic memory production as a strategic objective, encouraging collaboration among local semiconductor companies to reduce reliance on imported DRAM.
As part of this strategy, CXMT is reportedly sharing DRAM technology and manufacturing expertise with several domestic partners, including:
- JHICC (Fujian Jinhua Integrated Circuit Co.)
- Swaysure
- XMC, a subsidiary of Yangtze Memory Technologies (YMTC)
This collaborative approach is intended to accelerate China’s overall manufacturing capacity while strengthening the domestic semiconductor supply chain.
According to Citrini Research’s bottom-up manufacturing model, CXMT is simultaneously preparing for successive process-node migrations that will support long-term production growth.
Projected CXMT DRAM Capacity by Process Node (2030 Outlook) #
| Process Node | Projected Monthly Capacity |
|---|---|
| D1a | 400,000 wafers |
| D1b | 400,000 wafers |
| D1c | 150,000 wafers |
These projections represent current modeling assumptions and remain subject to changes in market demand, manufacturing yields, and China’s ability to access advanced semiconductor production equipment.
🏭 China’s Emerging DRAM Manufacturing Ecosystem #
While CXMT remains China’s flagship DRAM producer, several additional state-backed companies are expanding manufacturing capacity to establish a broader domestic memory ecosystem.
Swaysure #
Swaysure has completed construction of a DRAM fabrication facility in Shenzhen with an estimated manufacturing capacity of 140,000 wafers per month, positioning the company as an important contributor to China’s expanding memory supply chain.
JHICC (Fujian Jinhua) #
JHICC continues rebuilding its manufacturing capabilities following previous U.S. sanctions. Its Jinjiang fabrication complex is designed to support 120,000 wafers per month, with the first production phase targeting 60,000 wafers per month expected to complete equipment installation by the end of 2026.
XMC (YMTC Subsidiary) #
XMC, a subsidiary of Yangtze Memory Technologies, is expected to add approximately 50,000 wafers per month of DRAM capacity through its Wuhan Fab 3 facility, complementing China’s broader domestic memory production strategy.
🌍 China’s Position in the Global DRAM Industry #
Excluding fabrication plants in China owned by foreign companies such as Samsung Electronics and SK hynix, China’s domestically controlled DRAM manufacturing capacity is projected to reach approximately 600,000 wafers per month by 2026.
This expansion would establish China as the world’s second-largest domestic DRAM manufacturing base, significantly reducing the historical gap between Chinese memory suppliers and the industry’s established leaders.
The coordinated development of multiple fabrication facilities also reflects a strategic shift from reliance on a single national champion toward a diversified domestic manufacturing ecosystem capable of supporting broader supply-chain resilience.
⚖️ Geopolitical Challenges Remain #
Although production capacity is expanding rapidly, China’s ability to compete at the leading edge of DRAM technology remains closely tied to geopolitical developments.
Restrictions on advanced lithography systems, semiconductor manufacturing equipment, and electronic design technologies continue to limit access to the most advanced production processes. Future policy initiatives—including the proposed U.S. MATCH Act—could introduce additional constraints on technology transfers and supply-chain cooperation.
As a result, China’s challenge is no longer limited to building fabrication capacity. Sustained competitiveness will depend on successfully advancing process technology, improving manufacturing yields, and developing a more self-sufficient semiconductor equipment ecosystem.
🔍 Outlook #
CXMT’s projected rise to 350,000 wafers per month by 2026 represents one of the fastest capacity expansions in the global memory industry. Combined with growing investments from JHICC, Swaysure, and XMC, China is rapidly transforming from a major memory importer into a significant DRAM manufacturing powerhouse.
Whether this manufacturing expansion ultimately translates into leadership in advanced DRAM technology will depend on continued process-node innovation, equipment localization, and the evolving geopolitical environment. Nevertheless, China’s accelerating investment in domestic memory production is reshaping the competitive landscape of the global semiconductor industry and positioning the country as an increasingly influential force in future DRAM supply.
