CXMT Initiates Risk Trial Production of HBM3E Memory
Chinese memory manufacturer ChangXin Memory Technologies (CXMT) has reportedly initiated risk trial production of HBM3E memory. The company plans to scale up production rapidly, with full mass production potentially starting within a few weeks. This development marks a major milestone for China's domestic AI hardware supply chain, potentially easing reliance on foreign suppliers for critical AI accelerator components. However, industry analysts note that Chinese memory manufacturers still remain about two generations behind South Korean leaders like SK Hynix and Samsung. CXMT's HBM3E is expected to feature a 1024-bit width with typical speeds of 9.6 Gbps, delivering up to 1.2 TB/s of bandwidth. The company is also aggressively expanding its DRAM capacity, aiming for 350,000 wafers per month by the end of the year, aided by its ability to construct cleanrooms in just 12 months.
## BACKGROUND
High Bandwidth Memory (HBM) is a specialized 3D-stacked memory technology designed to provide high-speed data transfer for performance-oriented hardware like AI accelerators and GPUs. 'Risk production' is a preliminary manufacturing phase in the semiconductor industry used to test design viability and yield rates before committing to full-scale mass production.
