Higher performance, better efficiency, and enhanced reliability and security
LPDDR6 introduces a dual sub-channel architecture, each with 12 data lines and four command/address signals, designed to boost channel performance while minimizing physical footprint. It also includes features like static efficiency mode for high-capacity memory and on-the-fly burst length control, supporting both 32- and 64-byte data access. Dynamic write termination and flexible data routing further optimize signal integrity under changing workloads.
With increasing pressure to reduce power usage, LPDDR6 operates at lower voltages than its predecessor, LPDDR5. It introduces Dynamic Voltage Frequency Scaling for Low Power (DVFSL) and a single sub-channel mode for low-bandwidth operations. Alternating clock inputs and flexible refresh options further help minimize energy consumption.
The new standard builds on LPDDR5 with a suite of security upgrades. These include per-row activation counting for data integrity, on-die ECC (error correction code), link protection, and command/address parity. A new Carve-out Meta mode reserves memory regions for critical system functions, increasing overall reliability.
"JEDEC is proud to introduce LPDDR6, the culmination of years of dedicated effort by members of the JC-42.6 Subcommittee for Low Power Memories," said Mian Quddus, JEDEC's Chairman of the Board of Directors. He added, "By delivering a balance of power efficiency, robust security options and high performance, LPDDR6 is an ideal choice for next-generation mobile devices, AI and related applications to thrive in a power-conscious, high-performance world."
