ChangXin Memory Technologies (CXMT) has begun mass production of its fifth-generation DRAM platform, strengthening its position in a market dominated by Samsung Electronics, SK hynix and Micron. The platform reduces critical memory-cell pitch to 11.95 nanometers and produces at least 50% more functional dies per wafer than its previous generation. CXMT also said two 24-gigabit LPDDR5X products for smartphones and other portable devices had entered full-scale manufacturing, offering 50% more storage capacity and improved energy efficiency than predecessor chips. The company is separately preparing a research line for a possible move into NAND flash. Industry estimates put CXMT's second-quarter 2026 DRAM revenue share at 9.5% or 10%, depending on the research provider, while published reports said it generated 150.31 billion yuan, or about $22.4 billion, in first-half 2026 revenue.
