SK hynix will start LPDDR6 mass production in 2026 for Xiaomi smartphones

Q: When will SK hynix begin mass production of LPDDR6 and which smartphone maker is expected to be the first customer?

SK hynix will begin mass production of LPDDR6 in the second half of 2026. Xiaomi is expected to be the first customer, with the new memory reportedly destined for the companys next-generation flagship smartphone.

Q: What peak data transfer speed and efficiency improvements does LPDDR6 offer compared to LPDDR5X?

LPDDR6 targets a peak data transfer speed of 14.4 Gbps, which is about a 33% increase over LPDDR5X's 10.7 Gbps. Power efficiency is improved by more than 20% compared with LPDDR5X.

Q: Which process node is SK hynix using for its LPDDR6 and how does it compare to Samsung’s announced LPDDR6?

SK Hynix’s LPDDR6 is built on its sixth-generation 10nm-class process, known as 1c. Samsung’s announced LPDDR6 uses its 1b process, so SK Hynix is using a 1c process while Samsung is on 1b, and both companies are now racing to commercialize the standard. SK Hynix is targeting 14.4 Gbps and more than 20% better power efficiency for its 1c LPDDR6.

Q: How is LPDDR6 being adapted for AI servers and what is the SOCAMM module target capacity mentioned?

LPDDR6 is being adapted for AI servers via the SOCAMM module format, which aims to provide significantly lower power consumption than DDR5 while offering competitive bandwidth in compact server designs. JEDEC is targeting 512GB LPDDR6 SOCAMM modules for AI data centres.

The new standard hits 14.4 Gbps with 20% better efficiency, and SK Hynix is locking in Chinese smartphone customers like Xiaomi before CXMT closes the gap.

TL;DR: SK hynix will mass-produce LPDDR6 in H2 2026 using its 1c 10nm-class process, targeting 14.4 Gbps (≈33% faster than LPDDR5X) and over 20% better power efficiency via sub-channel architecture and Dynamic Voltage and Frequency Scaling. Xiaomi is expected as an early customer; SOCAMM LPDDR6 for AI servers aims for 2028 volume production.

SK Hynix is preparing to begin mass production of LPDDR6 memory in the second half of 2026, according to South Korean outlet Herald. Xiaomi is expected to become the first customer, with the new memory reportedly destined for the company's next-generation flagship smartphone.

LPDDR6 is built on SK Hynix's sixth-generation 10nm-class process, known as 1c. The company is targeting a maximum data transfer speed of 14.4 Gbps, a 33% improvement over the 10.7 Gbps ceiling of LPDDR5X. Power efficiency improves by more than 20%, achieved through two key design changes.

The first is a sub-channel structure that allows individual memory channels to operate selectively, engaging only the data paths that are actually needed at any given moment. The second is Dynamic Voltage and Frequency Scaling, which adjusts voltage and frequency dynamically depending on the workload rather than running at a fixed level.

LPDDR memory is also expanding into AI servers through the SOCAMM module format, which delivers significantly lower power consumption than DDR5 while offering competitive bandwidth in compact server designs. JEDEC is targeting 512GB LPDDR6 SOCAMM modules for AI data centres, and AMD has already confirmed its Zen 7 EPYC processors will support next-generation LPDDR memory. That means LPDDR6 SOCAMM needs to reach volume production by 2028.

Samsung announced its own LPDDR6 based on its 1b process in January, meaning both companies are now racing to commercialise the standard ahead of Micron. Meanwhile, China's CXMT is still working toward DDR6 production and is not expected to close the gap for several years. That gives SK Hynix an opportunity to lock in major Chinese smartphone customers such as Xiaomi, with Oppo and Vivo reportedly next in line.
