China’s leading NAND flash memory manufacturer, Yangtze Memory Technologies Co. (YMTC), is reportedly preparing a massive expansion of its production capabilities. According to sources familiar with the matter cited by Reuters, the company plans to construct three new fabrication plants in Wuhan, Hubei province. This strategic move is designed to more than double the firm’s current output, signaling a robust push for domestic semiconductor self-sufficiency amid ongoing geopolitical pressure from the United States.
The ambitious expansion plan outlines that each of the three new facilities will eventually reach a production capacity of 100,000 wafers per month once fully operational. Currently, YMTC operates two fabs with a combined monthly capacity of approximately 200,000 wafers. If the new projects proceed as planned, the company’s total output could surge to 500,000 wafers per month, significantly altering the global memory chip landscape.
Accelerating Domestic Semiconductor Production
The first of these new plants is expected to commence operations later this year. Sources indicate that construction on this initial facility has already been completed, and the installation of manufacturing equipment is currently underway. Notably, more than half of the tools being installed are sourced from domestic Chinese suppliers, highlighting the accelerated localization of the semiconductor supply chain. This facility is projected to reach a capacity of 50,000 wafers per month by 2027.
This aggressive capacity build-out comes at a critical juncture for China’s semiconductor industry. The United States has been steadily tightening export restrictions targeting advanced chipmaking capabilities, aiming to curb China’s technological advancement. YMTC itself was added to the US Department of Commerce’s Entity List in December 2022, a move that severely restricted its access to American technology and equipment.
In response to these constraints, YMTC has actively strengthened its partnerships with local equipment manufacturers. Companies such as Advanced Micro-Fabrication Equipment (AMEC) have become crucial allies in YMTC’s efforts to maintain and expand its production lines without relying on restricted foreign technology.

Reshaping the Global NAND Flash Market
YMTC’s expansion is not just a defensive maneuver; it represents a significant challenge to established global memory giants. According to a UBS report referenced in the recent coverage, YMTC captured an 11.8% share of the global NAND flash market last year. While Samsung remains the dominant leader with a 30.4% share, followed by SK Hynix, Kioxia, and Micron Technology, YMTC’s planned capacity increase could allow it to aggressively capture more market share, particularly in domestic and emerging markets.
The implications of this expansion extend beyond sheer volume. By scaling production, YMTC can achieve greater economies of scale, potentially driving down costs and increasing its competitiveness in the global market. Furthermore, reports suggest that YMTC is also exploring expansion into the DRAM segment, indicating broader ambitions to become a comprehensive memory solutions provider.
Navigating Geopolitical Headwinds
The timing of YMTC’s expansion is particularly noteworthy given the recent proposals by US lawmakers to implement further curbs on exports of semiconductor equipment to China. These proposed measures, which could take effect within 120 days, aim to limit expansion and technology upgrades in Chinese chip plants while allowing existing production to continue.
By accelerating the construction and equipping of its new fabs, YMTC appears to be racing against the clock to secure the necessary infrastructure before any new restrictions are enforced. The heavy reliance on domestic equipment suppliers for the new Wuhan plant demonstrates a strategic pivot towards a more resilient and self-contained manufacturing ecosystem.As the US-China tech war intensifies, YMTC’s expansion will serve as a critical barometer of China’s broader efforts to achieve semiconductor independence. The company’s ability to scale production using a higher proportion of domestic tools will be closely watched by industry analysts and policymakers alike.
