SK Hynix starts production of DRAM with 10-nm process technology

SK Hynix, the world’s second-largest memory chip producer, has started the production of DRAM with the latest 10-nanometer (nm) process technology.

SK Hynix said its 8 Gigabit Lower Power Double Date Rate 4 (LPDDR4) mobile DRAM is built on the 1anm node, using extreme ultraviolet (EUV) lithography technology.

The 1a is the fourth generation of the 10nm DRAM process solution following the 1x, 1y and 1z.

SK Hynix plans to supply the latest mobile DRAM products to smartphone makers from the second half of 2021, reports Yonhap news agency.

This was the first time that SK Hynix used the EUV equipment for mass production following its partial adoption for its 1ynm DRAM products.

SK Hynix plans to use the EUV technology for all of its 1anm DRAM production.

SK Hynix estimates the 1anm technology to give a 25 percent increase in the number of DRAM chips produced from the size of a wafer compared with the previous 1znm node.

The latest DRAM product stably supports 4266 megabits per second (Mbps), the fastest transfer rate in a standard LPDDR4 mobile DRAM speciation, and has reduced power consumption by 20 percent, according to the company.

SK Hynix will apply its 1anm node to its DDR5 products, the world’s first next-generation DRAM launched in October 2020, from early 2022.
