China's CXMT to begin advanced AI memory production despite low manufacturing yields

Chinese chipmaker CXMT is reportedly preparing to commence production of advanced AI memory chips, specifically HBM3E, despite facing significant manufacturing challenges. According to unnamed sources cited by Reuters, the company is pushing ahead with these plans even though its current production yields are notably low, with some reports suggesting a failure rate as high as 70%. This strategic move highlights China's imperative to develop domestic capabilities in high-bandwidth memory for artificial intelligence applications amidst global competition. While the exact timeline for mass production varies across reports, with one outlet specifying late Q4 2026, the initiative underscores a determination to overcome technical hurdles in a critical technology sector. The information primarily stems from industry sources, not direct company statements.
