CXMT Launches Advanced DDR5-8000 and LPDDR5X-10667 Memory Modules
At the 2025 China International Semiconductor Expo, Chinese semiconductor manufacturer CXMT introduced its first domestically developed DDR5-8000 and LPDDR5X-10667 memory modules. These new products represent a significant milestone for China’s memory industry, positioning CXMT alongside leading global memory manufacturers such as Samsung, SK Hynix, and Micron in terms of performance and technology.
Performance and Specifications
CXMT’s DDR5 memory modules operate at speeds of 8,000 MT/s, while the LPDDR5X modules reach up to 10,667 MT/s. This level of performance is on par with the latest offerings from Samsung, whose LPDDR6 memory matches the top speed of their LPDDR5X chips at 10,700 MT/s. The new CXMT modules are available in 12 Gb and 16 Gb LPDDR5X capacities, with DDR5 modules scaling up to 16 Gb and 24 Gb formats.
These memory chips are packaged in a variety of module types to serve different market needs. For data centers and enterprise servers, CXMT offers RDIMM, MRDIMM, and TFF MRDIMM modules. Mainstream desktops and PCs are supported by UDIMMs, while SODIMMs are designed for laptops and compact devices. For high-end overclocking and workstation applications, clock drive modules such as CUDIMM and CSODIMM are available. In the server segment, which represents the largest share of the market, CXMT’s RDIMMs provide a range of capacities to meet diverse platform requirements.
Technological Advancements in Chinese DRAM
In January, TechInsights identified CXMT’s new 16 nm DRAM chips in Gloway DDR-6000 UDIMM modules, highlighting a major step forward for China’s memory manufacturing capabilities. These 16 Gb DDR5 chips have a die size of 67 square millimeters and a density of 0.239 Gb per square millimeter. The G4 DRAM cells are 20 percent smaller than those in CXMT’s previous G3 generation, reflecting ongoing improvements in process technology. This progress builds on CXMT’s earlier advancements from 23 nm (G1) and 18 nm (G2) nodes.
Industry Context and Outlook
The expansion of China’s server infrastructure for both traditional computing and artificial intelligence has historically been limited by domestic silicon production capabilities. CXMT’s latest memory modules mark a significant step toward closing the gap with international competitors. However, despite these achievements, CXMT’s manufacturing technology remains approximately three years behind industry leaders Samsung, SK Hynix, and Micron. As a result, the global DRAM supply situation is unlikely to see immediate relief.
