SK Hynix presented the world’s fastest mobile DRAM so far

SK Hynix announced today that it has developed the world’s fastest mobile DRAM – LPDDR5T (Low Power Double Data Rate 5 Turbo) and provided sample products to customers. The new product, LPDDR5T, operates at a data rate of 9.6 Gbps that’s 13% faster than the previous generation LPDDR5X unveiled in November 2022. To highlight the maximum speed the product features, SK Hynix added ‘Turbo’ at the end of the standard name LPDDR5. LPDDR5T, which operates in the ultra-low voltage range of 1.01 to 1.12V set by the JEDEC (Joint Electron Device Engineering Council), is a product that not only features utmost speed but ultra-low power consumption.

SK Hynix said it provided customers with samples of 16GB multi-chip package, which combines multiple LPDDR5T chips into one package. The packaged product can process 77GB of data per second, which is equivalent to transferring fifteen FHD (Full-HD) movies in one second. SK Hynix plans to begin mass production of LPDDR5T using 1anm, the fourth generation of the 10nm technology, in the second half of the year. Meanwhile, SK Hynix has, again, integrated the HKMG (High-K Metal Gate) process in the latest product that enabled the new product to deliver the best performance, and expects LPDDR5T, which substantially widened the technology gap, “to lead the market before the development of the next generation LPDDR6.”
