SK hynix’s LPDDR5T Verified as World’s Fastest Mobile DRAM Using MediaTek’s Next-Gen Mobile Platform

SK hynix’s LPDDR5T (Low Power Double Data Rate 5 Turbo) has completed performance verification for application with MediaTek’s next-generation mobile APs. Developed in January 2023, the LPDDR5T is the world’s fastest mobile DRAM, achieving operating speeds of 9.6 gigabits per second (Gbps).

Defying Expectations to Achieve Groundbreaking Operating Speeds

SK hynix provided samples of its LPDDR5T to MediaTek, a leading global fabless semiconductor company, in February 2023 for testing. The performance tests were carried out using the next-generation MediaTek Dimensity flagship chipset, which is part of their Dimensity Platform series of mobile APs. Set to launch within this year, MediaTek’s next-generation flagship mobile chipset will utilize 9.6 Gbps memory—the fastest operating speed for mobile devices.

The global semiconductor industry had previously projected that operating speeds of up to 9.6 Gbps would only be achievable with future iterations such as the LPDDR6, which is scheduled to be released after 2026. SK hynix has expedited this timeline with the LPDDR5T.

Applied to a Range of Mobile Devices for 2024 Debut

As the standardization approval process with the Joint Electron Device Engineering Council (JEDEC) is already in its final stages, the LPDDR5T is gearing up for its full market debut. SK hynix predicts that the generational change of DRAM for mobile devices will accelerate from next year when products are standardized and market supply begins in earnest.

“As a result of our close collaboration with SK hynix, MediaTek’s next-generation flagship Dimensity chipset is the world’s first to be validated at LPDDR5T operating speeds up to 9.6Gbps, enabling upcoming devices to unleash an unprecedented level of mobile performance,”  said JC Hsu, Corporate Sr. Vice President and General Manager of Wireless Communications Business Unit at MediaTek. “Using this updated architecture, developers and users alike will be able to get more out of their devices than ever before.”

Sungsoo Ryu, head of DRAM Product Planning at SK hynix, said: “SK hynix’s partnership with MediaTek is set to play a key role in the LPDDR5T’s market entry. Starting with this performance verification, we will expand the scope of product supply to further strengthen the leadership of the mobile DRAM market.”
