CXMT (ChangXin Memory)
China's DRAM champion racing toward domestic HBM
ChangXin Memory Technologies is China's leading DRAM maker and the country's best hope for domestic HBM to feed Ascend and other AI chips. In 2025 CXMT began sampling HBM and ramping DDR5, a critical step to break dependence on Samsung, SK Hynix and Micron for AI memory. Under US export-control scrutiny, it is central to China's memory self-sufficiency.
