CXMT unveils 24-Gbit LPDDR5X products using new platform
China's largest DRAM maker is closing the gap with Samsung and Micron, one memory chip at a time
ChangXin Memory Technologies, China’s homegrown DRAM champion, has announced the launch of 24-Gbit LPDDR5X memory products built on a new platform.
What CXMT is actually building
The LPDDR5X lineup from CXMT spans 12Gb and 16Gb dies, with packaged solutions available in 12GB, 16GB, and 24GB capacities. The company also offers LPCAMM modules in 16GB and 32GB configurations, which are designed for thinner, more power-efficient laptops.
CXMT began mass production of LPDDR5X at speeds of 8,533 Mbps and 9,600 Mbps in May 2025. By October 2025, the company had moved to customer sampling for its top-tier 10,667 Mbps variant.
Compared to previous-generation memory, the LPDDR5X products deliver a 66% increase in bandwidth and roughly 30% reduction in power consumption.
At the International IC China expo in November 2025, CXMT showcased DDR5 products hitting speeds up to 8,000 Mbps with die densities of 24Gb.

From samples to smartphones
By mid-2026, CXMT’s LPDDR5X memory had entered commercial supply chains, powering devices including the Nubia NaviX Ultra, a flagship Chinese smartphone.
By September 2026, CXMT had initiated mass production of LPDDR6 memory, with Xiaomi’s Xiaomi 18 Fold among the early devices to adopt the next-generation standard.
CXMT operates multiple 12-inch fabrication facilities in Hefei and Beijing, with a production capacity target of approximately 300,000 wafers per month by the end of 2026.
The bigger picture: China’s memory ambitions
The three companies that dominate the global DRAM market, Samsung, SK hynix, and Micron, collectively control the vast majority of production. CXMT has been methodically climbing the technology ladder from DDR4 to LPDDR5X to LPDDR6.
The company is also reportedly exploring NAND flash technologies, which would give it a presence across both major categories of memory chips. Combined with plans for an eventual IPO, CXMT appears to be building toward something much larger than a niche domestic supplier.
