Chinese memory giant CXMT has been expanding its capacity so rapidly that the company is now able to compete with one of the largest memory manufacturers in the world—Micron. According to analysis from Citrini Research and their proprietary data, CXMT is projected to produce about 350,000 DRAM wafers per month by the end of 2026, assuming all current projects are completed on schedule. This is an impressive figure, especially considering that Micron, one of the "big three" DRAM manufacturers, is currently estimated to produce about 375,000 DRAM wafers per month by the end of 2026, assuming their capacity expansions are fulfilled. Micron has been a memory supplier for decades, while CXMT is a relatively new player that emerged to meet China's domestic needs.

A particularly surprising discovery is that CXMT is constructing its cleanrooms—where the actual silicon is produced—in just around 12 months, whereas the rest of the DRAM manufacturing industry typically takes 21-24 months, nearly a full year longer. The biggest challenge for Chinese memory makers like CXMT is acquiring advanced lithography solutions from around the world, as the United States government has imposed sanctions on the company and placed it on a blacklist, preventing access to modern EUV scanners. Instead, CXMT relies on older DUV lithography tools and uses multi-patterning techniques to work around the lack of EUV technology. Despite this, CXMT is matching Micron's output this year with nearly the same number of DRAM wafers, which is impressive for such a new market entrant.

Finally, the report notes that the Chinese government is encouraging CXMT to transfer its DRAM technology IP to other Chinese DRAM manufacturers such as JHICC, Swaysure, and YTMC's subsidiary XMC.
