Key Takeaways
- CXMT has officially begun mass production of LPDDR6 DRAM, becoming the first in the world to commercially deploy the standard in a mobile device.
- Xiaomi (01810) will be the debut customer, integrating the new memory into its upcoming Xiaomi 18 Fold flagship foldable smartphone.
- The Xiaomi 18 Fold is scheduled for a September 2026 release and will feature Xiaomi’s internally developed 3-nanometer Xring O3 processor.
- This partnership marks a significant milestone in China's semiconductor self-sufficiency, narrowing the technology gap with global leaders like Samsung Electronics and SK Hynix.
In a landmark development for the Chinese semiconductor industry, ChangXin Memory Technologies (CXMT) announced on Saturday that it has secured a supply agreement to provide its latest LPDDR6 DRAM chips for Xiaomi’s (01810) upcoming flagship foldable smartphone. The announcement, confirmed by both companies via social media, positions CXMT as the first memory maker to achieve commercialization of the LPDDR6 standard, ahead of traditional market leaders.
The new memory modules will debut in the Xiaomi 18 Fold, which is slated for an official launch in September 2026. This flagship device will also showcase Xiaomi’s (01810) in-house Xring O3 system-on-chip (SoC), a 3-nanometer processor specifically designed to support the high bandwidth and efficiency of LPDDR6 memory. Analysts note that the Xring O3 features approximately 24 billion transistors, a significant increase from previous generations, and is manufactured using TSMC’s advanced N3P process.
CXMT’s rapid ascent in the memory market is underscored by the fact that it began mass-producing LPDDR5 chips less than a year ago. The new LPDDR6 chips offer peak data transfer speeds of up to 12,800 Mbps, providing the necessary performance for intensive on-device artificial intelligence (AI) tasks and high-resolution foldable displays. While Samsung and SK Hynix have announced their own LPDDR6 solutions, CXMT’s early commercial entry with a high-volume client like Xiaomi (01810) represents a strategic shift in the global supply chain.
The financial implications for CXMT are already becoming apparent; the company recently reported a sharp swing to profit in the first half of 2026, with revenue surging 874% year-over-year to 150.3 billion yuan ($22.36 billion). Despite this growth, the company continues to face geopolitical headwinds, having recently filed a lawsuit against the U.S. Department of Defense to challenge its designation as a "Chinese military company."
Market experts suggest that the successful validation of CXMT’s high-end memory by Xiaomi (01810) could pave the way for broader adoption among other Chinese OEMs, such as Huawei and Honor. Furthermore, reports indicate that Apple (AAPL) has begun testing CXMT DRAM products for potential use in iPhones sold within the Chinese market, a move that would further challenge the dominance of the South Korean memory duopoly.
