Chinese DRAM maker CXMT only one to achieve mass production

Chinese memory module manufacturers are accelerating the release of consumer and enterprise storage products powered by domestic DDR5 chips, as breakthroughs by Changxin Memory Technologies (CXMT), the nation’s leading memory chipmaker, filter through the supply chain. Powev, one of China’s major memory module vendors, recently said its Sinker-branded DDR5 server memories had entered mass production and delivery. The 64GB DDR5-5600 RDIMM product passed testing by multiple major customers and was ready for bulk supply to enterprise clients, channel partners and branded vendors, the firm said. The company also introduced the Sinker DDR5 memory modules, said to fully use domestic components, while other Chinese vendors, including Comay, have released DDR5 products based on CXMT dies for industrial and enterprise applications.

In the consumer market, Powev’s Gloway and KingBank DDR5 models based on Chinese made DRAM chips were being sold as early as late 2024, marking one of the first visible signs that domestic DDR5 supply was moving beyond demonstration products and into commercial channels. The downstream push follows CXMT’s official debut of its DDR5 product portfolio in November last year. The Hefei-based company said its DDR5 chips supported speeds of up to 8,000 Mbps and die densities of 16 Gb and 24 Gb, targeting servers, workstations and personal computers. The 24 Gb density leaves CXMT roughly one generation behind the most advanced 32 Gb DDR5 chips from Samsung Electronics, SK Hynix and Micron Technology, but still represented a significant step forward for China’s domestic DRAM industry.

Founded in 2016 and headquartered in Hefei, Anhui province, CXMT is widely regarded as China’s only domestic DRAM maker to have achieved mass production. Its products span DDR memory used in servers and desktops, as well as Low-power DDR (LPDDR) for smartphones, tablets and wearable devices. Its LPDDR products have entered the supply chains of Chinese electronics makers including Xiaomi, OPPO, Vivo, Transsion and Lenovo.

CXMT is also moving towards a domestic listing to fund further expansion. On December 30, the Shanghai Stock Exchange (SSE) accepted the company’s application for a Star market initial public offering (IPO), with its prospectus showing a planned fundraising of CNY29.5 billion. The filing showed CXMT’s revenue rose 97.8% year-on-year to CNY32.08 billion in the first nine months of 2025, while its net loss narrowed to CNY5.98 billion from CNY6.84 billion a year earlier.

The latest product roll-outs come as the global memory industry enters one of its strongest up-cycles in years, driven by AI servers, high-bandwidth memory demand and tight conventional DRAM supply, the South China Morning Post reports.
