Xiaomi confirmed today that the Xiaomi 18 Fold will be the world’s first phone to ship with CXMT’s new LPDDR6 memory. The foldable is set to launch in September alongside the new SkyNomad SUV.
Xiaomi founder, chairman, and CEO Lei Jun announced the news on Weibo while congratulating CXMT on reaching mass production of LPDDR6. He called the achievement “remarkable” and said Xiaomi’s XRING O3 is the first chip to support the new memory standard. The Xiaomi 18 Fold will be the first device to use the technology.
Lei also said he expects more Chinese tech companies to work together on projects like this in the future. The XRING O3 itself only came out on August 24. Xiaomi unveiled it as the first chip in the industry built to work with LPDDR6.
What can you expect
According to IT Home, CXMT detailed the new memory in its 2026 semi-annual report. The company says LPDDR6 is a major upgrade over its previous LPDDR5X memory, with improvements to its architecture and data transfer system.
LPDDR6 can reach transfer speeds of up to 12,800Mbps and is available with up to 16GB of memory per chip. CXMT has already sent samples to key customers for testing and is now working to increase mass production.
Faster memory helps a phone handle multiple apps more smoothly, open apps faster, and deal with demanding AI features more efficiently. The move is also an important step for CXMT, which has been working to compete with major memory makers such as Samsung and SK Hynix. By supplying the first phone with LPDDR6, CXMT has secured an early lead in the new memory standard.
Xiaomi has not revealed the full specifications of the Xiaomi 18 Fold yet. However, with the foldable confirmed to launch in September, we should learn more about the phone soon.
