Chinese memory-chip maker CXMT says its fifth-generation DRAM manufacturing platform has entered mass production, a development that could strengthen China’s position in a market still dominated by Samsung Electronics, SK Hynix and Micron.
The company announced the production milestone at the 2026 World Manufacturing Convention, according to Reuters. CXMT also introduced two new 24-gigabit LPDDR5X memory products designed for smartphones and other portable devices.
More memory per chip, more dies per wafer
CXMT said the new platform uses a quadruple-patterning process that reduces memory-cell feature spacing to 11.95 nanometers. The company says the approach allows it to place more memory capacity on each chip while increasing the number of usable dies produced from a wafer.
According to CXMT, gross die output per wafer can improve by at least 50% compared with its previous generation. If those gains are sustained at commercial scale, they could help lower production costs and improve competitiveness in high-volume memory markets.
A strategic step for China’s semiconductor industry
The announcement comes as China continues to invest heavily in domestic semiconductor manufacturing amid U.S. restrictions on exports of advanced chipmaking equipment and technology. Memory has been a particularly important area because DRAM is used across smartphones, PCs, servers and AI infrastructure.
CXMT remains smaller than the industry’s three largest suppliers, but its ability to move newer manufacturing technology into volume production is closely watched by both competitors and policymakers. The company said the platform was developed with the help of simulation tools and collaboration with Chinese equipment suppliers.
LPDDR5X targets mobile and high-efficiency devices
The two 24-gigabit LPDDR5X chips unveiled alongside the manufacturing update are aimed at products where bandwidth and power efficiency are both important. CXMT says the new parts store 50% more data than its previous-generation products.
The broader significance will depend on yields, customer adoption and how quickly production scales. Still, the move signals continued progress in China’s effort to reduce dependence on imported semiconductor technology and expand its share of the global memory market.
