SK hynix just confirmed it’ll start mass-producing LPDDR6 memory in the second half of this year. The chips are built on the company’s latest 1c (10nm-class) DRAM process, and validation of the dies wrapped up recently. The first half of 2025 goes toward getting production lines ready.
The company has built 16 gigabit LPDDR6 chips aimed at smartphones and tablets running on-device AI. That’s where the speed bump matters most AI workloads are bandwidth-hungry, and LPDDR6 delivers a 33% improvement in data processing speed over LPDDR5X. Base operating speed sits at 10.7Gbps.
Power efficiency is the other half of the story. LPDDR6 cuts power consumption by at least 20% compared to the previous standard, and it does this through two specific methods.
First, a sub-channel structure that lets certain data paths go dormant when full bandwidth isn’t needed. Your phone isn’t always doing heavy processing, so there’s no reason every channel should be active during lighter tasks. Second, DVFS Dynamic Voltage and Frequency Scaling which drops the operating frequency and voltage during low-demand use and ramps both back up when you’re running AI tasks or gaming.
SK hynix says the combination should mean noticeably longer battery life and better multitasking on whatever devices ship with this RAM later this year.
