Overview

SK Hynix announced the successful development of its first LPDDR6 DRAM, delivering 33 % higher speed and 20 % better power efficiency than the previous‑generation LPDDR5X. The memory is manufactured on SK Hynix’s 10 nm‑class (1c) process node, introduced in 2024.

LPDDR6 Development Timeline

• July 2025 – JEDEC finalized and published the LPDDR6 standard.
• Eight months later – SK Hynix announced its LPDDR6 product, following Samsung’s earlier LPDDR6 announcement and CES 2026 showcase, which demonstrated speeds up to 10.7 Gbps.

Applications

Mobile Devices

SK Hynix confirmed that its 1c LPDDR6 will be used in upcoming smartphones and tablets.

Data Center & AI Servers

LPDDR X memory has already been popular in AI servers that employ SOCAMM and SOCAMM2 modules, which support LPDDR interfaces. Notable examples include:

• Nvidia GB300 Grace Blackwell Ultra Superchip – uses SOCAMM modules.
• Nvidia Vera Rubin Superchip – uses SOCAMM2 modules.

SK Hynix expects post‑Vera Rubin Nvidia AI chip designs to adopt LPDDR6, providing a significant performance boost for AI workloads.

Future Outlook

JEDEC projects that LPDDR6 data rates could reach up to 14,400 MT/s, far exceeding the current 10.7 Gbps implementations and surpassing the fastest DDR5 overclocking records.
