SK Hynix, one of the leading semiconductor manufacturers in South Korea, has just posted a blog update about the progress of DDR5 RAM – the new RAM standard that they have developed in collaboration with JEDEC. Accordingly, DDR5 RAM will have speeds ranging from 3200MHz to 8400MHz depending on the manufacturer. The first DDR5 RAM modules will have a speed of 4800MHz and will gradually increase from there. The minimum density of a DDR5 die is 8Gb and the maximum is 64Gb, which is four times that of DDR4.
Perhaps one of the biggest changes, aside from the improvements in capacity and speed, is that it supports Error-Correcting Code (ECC). Now, this feature will no longer be limited to special dies (like DDR4) but will be integrated into every DDR5 die. The DDR5 memory chip uses 32 banks, divided into 8 groups, maximizing the bandwidth of the RAM.
The Burst Length of DDR5 is 16, which is double that of DDR4, thus optimizing data retrieval. The operating voltage has also been reduced to 1.1V, helping to save 20% power compared to the 1.2V of DDR4. It is known that SK Hynix’s DDR5 chips will begin mass production in 2020, although the exact timing has not been disclosed yet.
