Chinese memory maker ChangXin Memory Technologies has begun mass production of next-generation LPDDR6 mobile memory, with Xiaomi’s upcoming foldable phone set to become one of its first major commercial applications. Reuters reported on August 29, 2026 that both companies confirmed CXMT’s LPDDR6 chips will be used in the Xiaomi 18 Fold, which is planned for release in September. The announcement marks a transition for the new mobile-memory standard from development and customer sampling toward a consumer product designed for large-scale sale.
LPDDR refers to a family of dynamic memory designed for low power consumption in smartphones and other portable devices. LPDDR6 is described as CXMT’s most advanced DRAM product for mobile hardware. The company moved to the new standard less than a year after beginning volume production of its previous LPDDR5 generation. Xiaomi’s decision also fits its strategy of taking greater control over key handset components. The company said the new foldable is expected to use its internally designed Xring O3 processor, produced on a three-nanometre-class process and built to support LPDDR6.
Information reported by Reuters and technology publication Gizmochina points to a September launch window for the Xiaomi 18 Fold. The complete specification sheet has not yet been released. Details such as battery capacity, camera hardware, price and international availability therefore remain outside the confirmed scope of the story. What has been established is Xiaomi’s plan to use CXMT memory in the foldable device and CXMT’s statement that LPDDR6 has entered mass production. The memory producer has also said it has delivered samples for customer evaluation.
A faster memory interface can increase the rate at which a phone’s processor exchanges data with applications and other system components. The practical benefit, however, will not be determined by memory speed alone. Processor design, software optimisation, thermal management and power controls will all affect performance and efficiency. It would therefore be premature to treat LPDDR6 as a guarantee of a specific battery-life improvement or a fixed increase in application speed. Measurable results will depend on the finished handset and independent testing after launch.
The development is also significant for China’s effort to expand the use of domestic components in its semiconductor supply chain. Placing CXMT’s newest memory in a high-volume consumer device will test the company’s manufacturing scale, consistency and customer qualification process. For Xiaomi, combining an internally designed processor with memory from a Chinese supplier could provide more control over component planning and product integration. Production yields, unit availability and the scope of sales outside China have not yet been disclosed, so the commercial reach of the partnership remains uncertain.
The companies’ August 29 statements identify September as the intended release month but do not provide a confirmed launch day. The development should therefore be understood as a verified component and manufacturing plan, not as a complete product-launch announcement. Xiaomi is expected to publish detailed specifications, pricing and market availability closer to the event, while CXMT may provide additional information about production capacity. This report relies on the companies’ confirmed statements as cross-checked by Reuters and avoids treating unverified social-media leaks as established facts.
