CXMT to begin HBM3E mass production despite low yields

China\'s largest DRAM maker ChangXin Memory Technologies (CXMT) will move to produce AI-focused high-bandwidth memory HBM3E despite low yields, Reuters reported on Tuesday. CXMT has sent HBM3E samples to Chinese AI chip design companies and plans to start small-scale production within two months. Yields are said to be 20 to 30 percent, versus about 70 percent for SK Hynix. Reuters said the move highlights severe AI memory shortages in China.
