Xiaomi’s upcoming flagship foldable smartphone will use advanced LPDDR6 memory chips made by China’s ChangXin Memory Technologies (CXMT), marking a significant development for China’s semiconductor industry.
CXMT announced that it will supply its latest LPDDR6 DRAM chips for Xiaomi’s 18 Fold, which is scheduled to launch in September. Xiaomi confirmed the partnership through its official Weibo account.
Editorial Insight
Key Highlights
Important points readers should notice.
Semiconductor progress: CXMT is rapidly closing the technology gap with major global memory-chip makers.
Domestic supply chain: Xiaomi is combining its own processor technology with Chinese-made memory.
Premium smartphone push: The 18 Fold gives CXMT an important platform in the high-end smartphone market.
Strategic shift: The partnership reflects China’s effort to reduce reliance on foreign semiconductor suppliers.
Industry impact: Faster development of domestic memory technology could strengthen China’s wider electronics ecosystem.
The development is significant because LPDDR6 is CXMT’s most advanced mobile DRAM technology. The company has moved into mass production of LPDDR6 less than a year after beginning mass production of its previous-generation LPDDR5 chips.
The new Xiaomi foldable is also expected to feature an updated version of the company’s in-house 3-nanometre Xring O3 processor, which supports LPDDR6 memory.
The combination of Xiaomi’s own processor technology and domestically produced advanced memory chips highlights Beijing’s broader push to reduce dependence on overseas semiconductor suppliers.
Editorial Analysis
Why This Matters
The Xiaomi-CXMT partnership shows that China is moving beyond smartphone assembly towards greater control over advanced processors and memory chips, two critical components of modern devices
For CXMT, securing a major smartphone customer such as Xiaomi represents an important step in expanding the use of its memory technology. The company said it has already shipped LPDDR6 samples for use in smartphones, servers and smart cars.
The development also comes at a time when CXMT is rapidly expanding its position in the global memory-chip market. The company reported revenue of 150.3 billion yuan ($22.36 billion) in the first half of 2026, an increase of 874% from a year earlier, according to Reuters.
CXMT’s progress is narrowing the technology gap between the Chinese company and major global memory-chip manufacturers such as Samsung and SK Hynix.
The Xiaomi partnership therefore carries significance beyond a single smartphone launch. It reflects the growing integration of Chinese-designed processors, domestic memory technology and locally developed hardware in premium consumer devices.
