CXMT's New Memory-Chip Platform Enters Mass Production, Boosting China's Chip Ambitions
- •Chinese DRAM chipmaker CXMT announced its fifth-generation technology platform has entered mass production, aiming to strengthen China's position against global leaders like Samsung, SK Hynix, and Micron Technology.
- •The new platform is designed for more powerful, cost-effective, and energy-efficient memory chips, providing an additional supply source for electronics manufacturers.
- •CXMT achieved a significant reduction in feature spacing to 11.95 nanometers using "quadruple patterning," bringing its process capability on par with advanced industry standards.
- •The company unveiled two 24-gigabit LPDDR5X products, offering 50% more data capacity than previous versions, already in mass production for smartphones and portable devices.
- •The new platform can produce at least 50% more gross chip dies per wafer than its predecessor, developed through computer simulations and collaboration with Chinese chip-equipment makers, amidst Beijing's drive for semiconductor self-reliance.
Key Questions Answered
CXMT announced that its fifth-generation technology platform has entered mass production, reducing feature spacing to 11.95 nanometres using quadruple patterning. This process capability matches the industry's most advanced mass-produced nodes, allowing more memory to fit on each chip and increasing gross chip dies per wafer.
CXMT unveiled two 24-gigabit LPDDR5X products built on its new platform, which are power-saving DRAM components used mainly in smartphones and portable devices. Each product holds 50% more data than previous equivalents and is already in mass production across two distinct package formats.
The breakthrough supports Beijing's goal to reduce reliance on foreign semiconductor technology, especially as US export controls since 2022 restrict access to advanced equipment. By improving process capabilities, CXMT aims to build a stronger domestic competitor against global industry giants like Samsung Electronics, SK Hynix, and Micron Technology.
