SK Hynix Inc. Announces 1Ynm 16Gb DDR5 DRAM

SK Hynix has announced that the company has developed 16Gb (Gigabits) DDR5 (Double Data Rate 5) DRAM, the industry's first DDR5 to meet the JEDEC standards. The company used the same 1Ynm process that it used to create 8Gb DDR4 DRAM for a competitive edge over the competition. "DDR5 is a next-generation DRAM standard that offers ultra-high speed and high density with reduced power consumption as compared to DDR4, for use in data-intensive applications such as big data, artificial intelligence, and machine learning." SK Hynix is already supplying major chipset makers with modules for servers and PC platforms with up to 32 memory banks per JEDEC DDR5 standards. The DDR5 modules are expected to be mass produced in 2020 and DDR5 will have a 44% total DRAM market share by 2022.

SK Hynix successfully lowered the operating voltage from 1.2V to 1.1V, achieving 30% lower power consumption compared to the previous generation, DDR4 DRAM. The new 16Gb DDR5 DRAM supports a data transfer rate of 5200Mbps, about 60% faster compared to 3200Mbps of the previous generation, with which it can process 41.6GB (Gigabytes) of data--11 full-HD video files (3.7GB each)--per second.
