Until the second 2023 half LPDDR5T will be the fastest mobile memory standard with a transfer rate of 9.6 Gbps per chip and 77 GB/s per 16 GB packet. SK Hynix will mass-produce this type of memory on its latest 10nm nodes with High-K Metal Gate technology.

The fastest LPDDR5X memory currently available with a transfer rate of 8.5 Gbps was introduced in 2022. at the end, but now, just a few months later, SK Hynix is ​​pushing the envelope further with an even faster iteration called LPDDR5T. To better emphasize the transfer rate, which can reach up to 9.6 Gbps (13% faster than LPDDR5X), SK Hynix changes the suffix X to T for Turbo.

Because LPDDR5T chips are designed for handhelds and ultrabooks, they operate at ultra-low voltages of 1.01 to 1.12 V. The standard 16 GB multi-chip package is designed for 77 GB/s transfer speeds. The new type of memory is expected to begin mass production on SK Hynix’s fourth-generation 10nm nodes in 2023. on the other side. Thanks to the integration of the High-K Metal Gate film into the DRAM transistors, SK Hynix can ensure the lowest power consumption while still improving the transfer speed.

Due to the large jump in transfer rates, LPDDR5T memory can be useful not only for 5G handhelds and ultra-thin laptops, but also for artificial intelligence and machine learning applications, as well as VR/AR. This would be the last iteration of SK Hynix’s LPDDR5 standard, as the South Korean company plans to continue focusing on LPDDR6.
