CXMT Starts Limited LPDDR6 Output in September for Xiaomi 18 Fold, Targeting Fewer Than 500,000 Units

Summary
September is set to mark CXMT’s limited LPDDR6 mass production, with the memory initially reserved for Xiaomi’s 18 Fold rather than a broad smartphone rollout.
Fewer than 500,000 units are expected for the foldable, and one estimate puts XRING 03 shipments below 300,000, signaling that CXMT’s first LPDDR6 program will be low-volume.
U.S. trade restrictions are a key constraint: CXMT is relying on legacy DUV tools and multi-patterning, which raise costs and make it harder to scale output while preserving yields.
That still gives CXMT an early design win with Xiaomi and potentially Huawei, but the bigger test is whether it can expand production before Samsung, SK hynix and Micron close the gap.
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.
