The RAM uses LPDDR4 technology and the 10 nm process. The arrival of 64-bit processors has allowed phone RAM to increase beyond 4GB but few manufacturers could be bothered. Even Samsung passed on it. However, now it seems that with the new generation of RAM Samsung thinks it is worthwhile and will be jumping directly from 4 to 8GB by next year.
LPDDR4 is currently the fastest type of low power memory in the mobile market. Samsung says it is the same as PC-class DDR4 RAM and has twice the speed, operating at 4,266 Mbps, versus the PC’s 2,133 Mbps.
By using 10 nm processing, the DRAM only takes up 15 x 15 x 1 mm and can be stacked above or under other chips. While we can’t see the point of the technology in mobile phones, it does make a lot of sense in tablets.
While Samsung has hinted that it is going to release the technology on the mobile world, by the end of the year so we should see next year’s flagship models with 8Gb next year.
