Last year Samsung and SK Hynix both announced their 8GB LPDDR4 mobile DRAM, and Asus has just shown off the industry’s first smartphone featuring 8GB LPDDR4, ZenFone AR. SK Hynix decided to take it further by launching the world’s first highest density of 8GB LPDDR4X mobile DRAM using its state of the art dual channel 16Gb chips.
Compared to the current LPDDR4, the new DRAM delivers 20% better power efficiency. Data I/Os run at ultra-low voltage of 0.6V in the LPDDR4X compared to 1.1V in LPDDR4. The 8GB LPDDR4X processes 34.1GB of data per second with 64-bit I/O.
Furthermore, the package size is the smallest ever (12mm*12.7mm), which is scaled down by more than 30% compared to an 8GB LPDDR4 with the thickness thinner than 1mm.
The company expects the product to be installed in a variety of mobile devices and optimize user conveniences with the virtue of the efficiency in battery use, the high performance, and the compactness.
For now only Qualcomm Snapdragon 835 and MediaTek Helio P20 can use LPDDR4X, but demand for 8GB mobile DRAM will undoubtedly increase this year, and probably occupy the biggest share in the high-end smartphones.
