GoKawiilFollowing its massive $8.6 billion initial public offering (IPO) in July, ChangXin Memory Technologies (CXMT) began considering building its sixth DRAM fab in China to boost memory output in the coming years, Reuters reports. If all announced projects proceed as planned, the company's production capacity could more than double in the mid-term future, the report claims. Meanwhile, investment banker Dan Niles believes China could capture 30% of the DRAM market by 2030, according to P Equity Research.
Growing at a rapid pace
CXMT currently operates three 300-mm DRAM fabs: two near Hefei and one in Beijing's Yizhuang district. Unofficial reports claim that each fab is capable of processing around 100,000 wafers per month, so the company's output may be around 300,000 wafer starts per month (WSPM).

The company is pursuing an aggressive expansion strategy and is currently building additional fabs near Shanghai and Hefei, according to Reuters. The company's sixth fab will reportedly be located in Beijing's Yizhuang area, adjacent to its existing facility. Once these projects are fully operational, the company’s total manufacturing capacity could exceed 600,000 WSPM, which will double its current output, according to Reuters. Meanwhile, researchers from Citrini believe that CXMT could exit 2026 with a capacity of 350,000 WSPM, which is just 25,000 WSPM shy of what Micron targets by the end of the year. Citrini Research models that by 2030, CXMT will have production capacity of around 950,000 WSPM.

Building three big DRAM fabs is a big deal, from both financial and execution points of view. However, it is not a secret that virtually all fabs owned by Chinese companies are built using money from local and federal governments under the 'Hefei model,' which aims to transform cities into economic juggernauts by leveraging high-risk projects. So it is not surprising that both Shanghai and Beijing have provided financial assistance and other forms of support to attract CXMT to their regions, according to Reuters.
CXMT's existing Beijing fab, operated by Changxin Jidian, received backing from E-Town Capital and Beijing E-Town Technology, both affiliated with the Yizhuang development zone, according to a person familiar with the matter cited by Reuters. In fact, the district has evolved into a relatively major semiconductor manufacturing hub that already hosts CXMT, SMIC, Naura Technology, and Xiaomi, the report claims.
The right timing
The proposed fab would be located in Beijing's Yizhuang district, roughly 20 kilometers southeast of the city center, where CXMT already operates a 300-mm DRAM manufacturing facility. The planned production capacity and total capital investment for the project have not yet been disclosed, although Reuters points out that a leading-edge DRAM fab typically costs well over $10 billion.
