ChangXin Memory Technologies (CXMT), China’s leading memory chipmaker, has started mass production of a new generation of DRAM products in the latest sign of the country’s advancing semiconductor capabilities.
The Hefei-based company, which is preparing for an initial public offering in Shanghai, announced on its official website that it had begun producing LPDDR5X – an advanced type of DRAM widely used in mobile devices.
DRAM chips function as high-speed memory in artificial intelligence systems, allowing rapid storage and access to the vast amounts of data required for AI model training and inference.
CXMT’s move marks its entry into the global arena for advanced memory chips, a market long dominated by South Korea’s Samsung Electronics and SK Hynix, as well as US-based Micron Technology.
The company’s LPDDR5X range includes chips with speeds of 8,533 Mbps, 9,600 Mbps and 10,667 Mbps. Mass production of the first two models began in May, while the fastest version was currently in the “customer sampling” stage, CXMT said in the statement.
The LPDDR5X series is an upgrade on CXMT’s LPDDR5 line-up, offering faster data transfer rates and lower power consumption. The firm launched its LPDDR5 family in 2023, including 12Gb dies and 6GB and 12GB mobile DRAM packages.
