CXMT Starts LPDDR6 Mass Production, Xiaomi 18 Fold First at 10,667 Mbps

Summary
CXMT said Friday it has begun mass production of LPDDR6, with Xiaomi’s 18 Fold—due in September—set to become the first device to ship with the new memory.
10,667 Mbps LPDDR6 on a 4×24-bit interface delivers about 113.8 GB/s of peak bandwidth, according to Xiaomi’s earlier specifications for the phone.
That setup gives the XRING O3 chip in the 18 Fold 48% more memory bandwidth than XRING O1, while putting CXMT ahead of Samsung, SK Hynix and Micron in launching LPDDR6.
LPDDR6 is starting at transfer speeds similar to top-end LPDDR5X, but its wider bus should lift bandwidth immediately, with the standard expected to scale to 14.4 Gbps and beyond.
How will Xiaomi's new XRING O3 chip utilize LPDDR6's massive bandwidth to redefine on-device AI performance against established tech giants?
With rivals holding validated silicon, is CXMT's LPDDR6 mass production a true industry disruption or just a clever marketing illusion?
Breaking the Memory Oligopoly: CXMT’s 12.8 Gbps LPDDR6, Xiaomi’s Domestic Flagship, and the New Era of Chinese Semiconductor Self-Reliance
Overview
In September 2026, Xiaomi will launch the Xiaomi 18 Fold, the world’s first device to feature CXMT’s mass-produced LPDDR6 memory. This breakthrough follows Xiaomi’s strategic investment in CXMT and comes as global AI demand has pushed up memory costs and squeezed Xiaomi’s profits. By securing CXMT as a domestic supplier, Xiaomi aims to stabilize costs and hedge against volatile global prices. However, due to export restrictions, CXMT relies on older DUV lithography, making its LPDDR6 slower and more expensive to produce than global competitors. Despite these challenges, the Xiaomi-CXMT partnership marks a major step toward China’s self-reliance in advanced memory technology.
