SK Hynix develops 8Gbit DDR4 memory on an updated 10nm class process

SK Hynix reports the arrival of DDR4 memory of 8Gbit on a ‘1Ynm’ production process. Thanks to the improved 10nm class process, the chips should perform better and consume less. SK Hynix follows Samsung in this area.

According to SK Hynix, the 8Gbit chips are fifteen percent more efficient than the DDR4 chips that SK Hynix has made so far on a 10nm class production process. The term ’10nm-class’ is used by chip manufacturers to designate production processes between 10 and 19nm. Until now, SK Hynix made 8Gbit chips for ddr4 in a process it called 1Xnm, where the X represents a high number. In the new 1Ynm process, the Y stands for the 4, 5 or 6.

The throughput of the 8Gbit chips is 3200MT/s. According to SK Hynix, the chips will hit the market in the first quarter of 2019. Initially, the Korean company serves the market for servers and PCs; at a later stage, the chips should also appear for ddr4 memory for smartphones and tablets.

SK Hynix is ​​lagging behind competitor Samsung in development. It announced a year ago that it would make 8Gbit DDR4 on a renewed 10nm class process. Those chips have a maximum throughput of 3600MT/s, where the first generation reached 3200MT/s.
