SK hynix has developed LPDDR5X (Low Power Double Data Rate 5X), the world's first-ever mobile DRAM with an integrated HKMG (High-K Metal Gate) process, which was just recently introduced to the market. The LPDDR5X boasts the industry's highest energy-efficiency as SK hynix succeeded in reducing power consumption by 25% compared to the previous generation and operates in the ultra-low voltage range of 1.01 V to 1.12 V set by the JEDEC (Joint Electron Device Engineering Council).
For the LPDDR, which is also called a mobile DRAM, having a low power consumption is its greatest asset, just as its standard name—LP (Low Power)—suggests. As power is limited in mobile devices, it's necessary to reduce power consumption as much as possible to extend the usage time.
This is why lowering power consumption is just as important as increasing operating speed. LPDDR5X was the first among mobile DRAMs to integrate the HKMG process and see improved performance and a reduction in power consumption, essentially killing two birds with one stone. As the power consumption of DRAM gets lowered by LPDDR5X, mobile devices can be used for a longer time with a single charge. The reduction in power consumption of such products can subsequently lead to a reduction in the power used by consumers, which is in line with the value of SK hynix's ESG-centered business management.
