JEDEC (Solid State Technology Association) has officially announced LPDDR6, its long-term, low-power memory technology. The next-generation memory architecture, standardized under the codename JESD209-6, is designed specifically for mobile devices, artificial intelligence applications, and systems requiring low power consumption. LPDDR6 offers significant improvements over its predecessors in performance, efficiency, and security.
LPDDR6 standard introduced
The new standard features two 12-bit sub-channels with four command/address lines each. This structure increases data transfer efficiency per channel while allowing for more simultaneous processing. Its 32-byte access granularity and flexible data access structure reduce memory access latency. This ensures more stable performance, particularly in high-speed mobile applications and real-time AI tasks.
LPDDR6 introduces significant innovations in both performance and energy efficiency. With the new low-voltage power supply (VDD2) and DVFSL (Dynamic Voltage and Frequency Scaling for Low-power), the memory module can automatically lower its frequency and voltage in different usage scenarios.
The system increases static and dynamic energy efficiency by operating only active sub-channels. This structure extends battery life in mobile devices while balancing energy usage as needed during periods of high processing power requirements.
New measures are also implemented with LPDDR6 for security and system stability. Features such as carriage return activation tracking (PRAC), command and address parity, embedded error-correcting code (ECC), and embedded memory test system (MBIST) ensure more secure and stable memory operation. Carve-out Meta mode support is also available, specifically for use in AI tasks. This feature allows for the creation of dedicated memory regions for critical tasks.
LPDDR6 is expected to be widely used in high-end smartphones, tablets, wearables, and AI-enabled hardware coming in 2025 and beyond. The new standard opens the door to more powerful and energy-efficient systems for device manufacturers.
