China’s CXMT shares rise as new DRAM platform enters mass production

Shares of Chinese memory chipmaker ChangXin Memory Technologies (CXMT) surged on Monday following the company's announcement that its fifth-generation dynamic random-access memory (DRAM) technology platform had entered mass production. The G5 platform, showcased at the 2026 World Manufacturing Convention in Hefei, was joined by two new LPDDR5X memory products tailored for smartphones and portable consumer electronics. The Shanghai-listed CXMT stock climbed 2.6% to 56.97 yuan by 05:16 GMT.

CXMT disclosed that the platform's memory-array half-pitch had reached 11.95 nanometres, while its die-per-wafer output had surged by at least 50% compared to its predecessor. This enhancement enhances power efficiency and bolsters cost competitiveness. Both LPDDR5X products feature 24 gigabits per die, marking a 50% increase over the preceding generation's comparable offerings, according to CXMT.

The new platform bolsters supply-chain resilience and brings CXMT's process technology closer to the industry's most advanced mass-production memory platforms.

The announcement arrives as Chinese chipmakers strive to lessen their dependence on overseas suppliers due to U.S. restrictions on advanced semiconductor technology.
