ChangXin Memory Technologies has ramped up its LPDDR5X production, marking a strategic move in narrowing the gap with established global memory giants and expanding China’s domestic memory supply chain.
ChangXin Memory Technologies has moved its LPDDR5X line into higher volume production, a notable step for China’s largest DRAM maker as it tries to narrow the gap with Samsung Electronics, SK hynix and Micron. The company says its latest platform covers 12Gb and 16Gb dies, with packaged parts in 12GB, 16GB and 24GB formats, alongside LPCAMM modules aimed at thin-and-light laptops. According to CXMT, the range is fully backward compatible with LPDDR5.
The technical progression has been rapid. CXMT said it began mass production of LPDDR5X parts running at 8,533Mbps and 9,600Mbps in May 2025, before extending sampling to a 10,667Mbps version later that year. The company has also described the new generation as delivering about 66% more bandwidth and roughly 30% less power consumption than its previous products, a combination that matters most in mobile devices and portable PCs.
That is beginning to show up in products. CXMT said its LPDDR5X chips had entered commercial supply chains by mid-2026, including use in the Nubia NaviX Ultra smartphone. At the same time, the company has widened its portfolio beyond mobile memory. At the China International Semiconductor Expo in November 2025, it showcased DDR5 devices with speeds of up to 8,000Mbps and die densities of up to 24Gb, underscoring an effort to compete across both server and consumer memory segments.
The broader significance is strategic as much as technical. The global DRAM market remains heavily concentrated, with Samsung, SK hynix and Micron still dominating output. CXMT is trying to move methodically from DDR4 into LPDDR5X and now LPDDR6, while also building out manufacturing capacity in Hefei and Beijing. Reports have also pointed to possible interest in NAND flash, which would expand the company beyond DRAM and deepen China’s ambition to build a fuller domestic memory supply chain.
