SK hynix unveiled the “world’s fastest mobile DRAM”, which it calls LPDDR5T. The “T” stands for “Turbo” as the new RAM chips are 13% faster than the LPDDR5X RAM that has recently started appearing on premium devices.
LPDDR5T runs at 9.6Gbps compared to 8.5Gbps for 5X and 6.4Gbps for the original LPDDR5. At this speed the new RAM can go through 77GB worth of data in one second.
Note that 5T is not a new generation of DRAM but rather an enhancement of 5X. The chips are based on the 1Anm process, the fourth generation of the 10nm node and use the HKMG (High-K Metal Gate) process that reduces power usage and increases speed. HKMG for DRAM chips was introduced by SK first with its 5X chips from last year.
The company has already sent samples to its partners – 16GB multi-chip packages (they combine several LPDDR5T chips in one package). SK hynix plans to start mass production of 5T RAM in the second half of this year.
The faster RAM will be featured in smartphones, of course, but the company sees applications in AI and AR/VR as well.
