SK HYNIX DEVELOPS WORLD’S FASTEST MOBILE DRAM LPDDR5T

SK hynix Inc. announced 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 gigabits per second (Gbps), 13% faster than the previous generation LPDDR5X1 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 the utmost speed but ultra-low power consumption.

SK hynix provided customers with samples of 16 gigabyte (GB) 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. The mass production of LPDDR5T using 1anm, the fourth generation of the 10nm technology, is slated to begin 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.

The IT industry forecasts increasing demand for memory chips with advanced specifications as the 5G smartphone market expands further. In this trend, SK hynix expects the application of LPDDR5T to expand beyond smartphones to artificial intelligence (AI), machine learning and augmented/virtual reality (AR/VR).
