SK hynix Inc. (or “the company”, www.skhynix.com) announced that it has begun supplying the industry’s first 24-gigabyte (GB) Low Power Double Data Rate 5X (LPDDR5X1) mobile DRAM package to its customers, following the mass production of LPDDR5X in November 2022.
LPDDR: Low Power DRAM for mobile devices, including smartphones and tablets, aimed at minimizing power consumption and features low voltage operation. LPDDR5X DRAM is the 7th generation product, succeeding the series of such that ends with 1, 2, 3, 4, 4X and 5. SK hynix, in January, developed LPDDR5T, which is an upgraded product of LPDDR5X prior to the development of the 8th generation LPDDR6, and is currently processing customer validation.
“The company integrated the High-K Metal Gate (HKMG2) process in the 24 GB LPDDR5X package, enabling the product to deliver outstanding power efficiency and performance,” said SK hynix. “The addition of the 24GB package to our mobile DRAM product portfolio has given us a more flexibility in accommodating customers’ needs.”
HKMG: A next-generation process that uses a material with a high dielectric constant (K) in the insulating film inside DRAM transistors to prevent leakage currents and to improve capacitance. It reduces power consumption while increasing speed. SK hynix had become the industry’s first to integrate the process in mobile DRAM in Nov. 2022.
The 24GB LPDDR5X package operates in the ultra-low voltage range of 1.01 to 1.12V set by the Joint Electron Device Engineering Council (JEDEC), and can process 68GB of data per second, which is equivalent to transferring 13 FHD (Full-HD) movies in one second.
SK hynix, prior to today’s announcement, has begun supplying its new product to smartphone manufacturer OPPO since last month. OPPO’s latest flagship smartphone ‘Oneplus Ace 2 Pro’, which features SK hynix’s 24GB LPDDR5X package, was launched on August 10th.
