"Micron’s leadership in delivering the industry’s first low-power DDR5 DRAM for use in a smartphone will accelerate enablement of 5G and AI applications," said Dr. Raj Talluri, senior vice president and general manager of the Mobile Business Unit at Micron. "Our customers and partners require next-generation memory solutions, based on the latest process technology, that drive unmatched power and performance to support 5G and AI systems."
Micron's fastest LPDDR4x solutions can hit 4,266Mbps per pin. The jump to LPDDR5 bumps things up to 5.5Gbps and 6.4Gbps, depending on the specific package. Micron says it has begun shipping LPDDR5 to customers in 6GB, 8GB, and 12GB capacities, at those speeds.
Looking ahead, Micron anticipates its memory being available in a UFS-based multichip package (uMCP5) for use in both high-end and even mid-range phones. Micron touts longer battery life as one of the benefits, though we imagine it will be a nominal gain. The performance gains are more interesting to us, and it will be interesting to see how smartphone manufacturers leverage them.
