ChangXin Memory Technologies (CXMT) has begun mass production of its self-developed LPDDR6 memory chips, with the first commercial deployment in Xiaomi's 18 Fold flagship foldable smartphone. This marks the world's first LPDDR6 product to reach commercial use in a flagship device, breaking overseas vendors' long‑standing monopoly on next‑gen memory standard launches .
The LPDDR6 chip, compliant with the JEDEC LPDDR6 standard, delivers a peak data rate of 12,800 Mbps and reaches 10,667 Mbps when paired with the SoC – offering 60% higher bandwidth and 20% lower power consumption compared to LPDDR5X . The initial commercial version is a 16GB package built on 16Gb dies, using a 1,295‑ball FBGA package .
Key technological innovations:
Dual‑channel architecture with 24‑bit native I/O, reducing access latency
Dual‑rail DVFS for dynamic voltage scaling across different load scenarios
High‑K EMC molding compound cutting thermal resistance by ~40% for sustained high‑load performance
Enhanced reliability features including PRAC row‑hammer protection and MBIST self‑test
The chip is paired with Xiaomi's in‑house Xring O3 SoC, the industry's first mobile processor to support LPDDR6 . Xiaomi CEO Lei Jun publicly praised CXMT's achievement, stating this cooperation marks "just the beginning" of stronger collaboration among Chinese tech companies .
Beyond smartphones, CXMT expects LPDDR6 to expand into PCs, smart vehicles, edge servers, and robotics as on‑device AI drives demand for high‑bandwidth, low‑power memory .
ICgoodFind Takeaway:
CXMT's LPDDR6 mass production puts China's memory industry on the global first‑wave map for a new DRAM standard. The Xiaomi collaboration demonstrates supply‑chain validation at the flagship tier – a key reference for procurement teams tracking domestic memory alternatives.
