Die Die my darling

SK Hynix has released more info on its upcoming DDR5 memory, which it has developed in correspondence with JEDEC's progression of the standard and it quadruples the maximum capacity of DDR4 dies.

The top speed is 8400 Mbps - if it is going downhill and the wind is behind it - but the standard is flexible which means manufacturers can release chips with frequencies ranging anywhere from 3200-8400 Mbps. The minimum density of a single DDR5 die is 8 Gb, while the maximum is 64 Gb which is four times the maximum capacity of DDR4 dies.

Another change is Error-Correcting Code (ECC) support for memory. This feature is now not exclusive to special dies, but will be under the bonnet of all of them. The DDR5 memory chips use 32 banks, split into eight bank clusters. This is supposed to provided better bandwidth. Its Burst Length is 16, compared to 8 of DDR4, so memory access availability is better.

Operating Voltage is decreased to 1.1 V, from the previous 1.2 V of DDR4, resulting in an overall decrease of 20 percent of power consumption. SK Hynix mass production of SK-Hynix's DDR5 chips will start this year, although no one is saying when.
