CXMT begins LPDDR6 mass production for Xiaomi 18 Fold

LPDDR6 CXMT Xiaomi 18 Fold DRAM mass production semiconductor industry

Chinese chipmaker ChangXin Memory Technologies (CXMT) has announced the commencement of mass production for its next-generation LPDDR6 mobile DRAM. This development positions CXMT as a first-mover in the commercial deployment of this memory standard, ahead of major competitors including Samsung Electronics, SK hynix, and Micron.

Xiaomi has confirmed that its upcoming flagship foldable smartphone, the Xiaomi 18 Fold, will be the first device to utilize CXMT's LPDDR6 technology. The device is expected to launch in September and will feature Xiaomi's proprietary Xuanjie O3 processor, which is designed to support the new memory standard. The LPDDR6 chips are reported to reach speeds of up to 12,800Mbps with a maximum capacity of 16Gb.

Industry analysts suggest that the partnership allows Xiaomi to reduce its reliance on international chip suppliers while providing CXMT with a high-end test bed for its technology. However, some experts note that initial production volumes may be limited, with shipment estimates for the Xiaomi 18 Fold ranging between 200,000 and 300,000 units. While rivals like SK hynix and Samsung have developed LPDDR6, they have yet to announce specific commercial handset deployments tied to mass production.
