China's CXMT says new memory-chip platform enters mass production

CXMT, China's leading producer of DRAM, said the new platform packs the tiny structures that store data closer together, allowing more memory to fit on each chip and more individual chips to be made from each silicon wafer.

The Hefei-based memory-chip maker said it had reduced the spacing of key features in the part of the chip that stores data to 11.95 nanometres, or about 12 billionths of a metre.

It achieved this using "quadruple patterning," a process that repeats several manufacturing steps to produce finer circuit patterns.

"Our process capability is now on par with the most advanced mass-produced nodes out there in the industry," Luo Xiaodong, CXMT's vice president and head of its marketing centre, said at the 2026 World Manufacturing Convention in Hefei.

CXMT also unveiled two 24-gigabit LPDDR5X products made on the new platform. LPDDR5X is a power-saving type of DRAM used mainly in smartphones and other portable electronics.
