ChangXin Memory Technologies (CXMT) has started small-batch production of high-bandwidth memory (HBM) chips based on the HBM3E standard, according to industry reports. The move positions the company as the first Chinese firm to produce the advanced memory technology, though it remains a generation behind global leaders SK Hynix, Samsung Electronics, and Micron Technology.
CXMT, established in 2016 with backing from local governments, is China’s fourth-largest standard DRAM manufacturer. Its HBM3E silicon is currently undergoing integration testing with domestic chip designers, including Alibaba Group’s T-Head unit and Cambricon Technologies. Commercial deployment is anticipated as early as 2025, with broader availability targeted by 2027.
The company faces significant operational challenges, including low manufacturing yields, restricted access to advanced fabrication equipment, and Western trade sanctions that limit procurement of cutting-edge semiconductor tools. These constraints have not deterred CXMT’s rapid financial growth, fueled by a landmark Shanghai initial public offering in February.
CXMT raised $8.6 billion in its IPO, the proceeds of which are being directed toward capital expenditure and technology development. Shares surged 472% in their trading debut. First-half revenue reached 150.3 billion yuan ($22.3 billion), nearly tenfold year-over-year, while net profit totaled 77.6 billion yuan ($11.5 billion), reversing a year-earlier loss.
The report, originally from The Information, underscores China’s push for self-reliance in semiconductor production amid ongoing geopolitical and technological constraints.
