SK Hynix, the second largest chipmaker in South Korea, announced the launch of the world's highest density 8GB LPDDR4X mobile DRAM on Monday.

The 8GB LPDDR4X mobile DRAM was manufactured using the company's dual channel 16Gb chips. SK Hynix has been planning to mass produce the product for upcoming flagship smartphones equipped with 8GB mobile DRAM. 8GB is the highest density in the LPDDR4X standard, which has 20% of superiority in power efficiency to current LPDDR4.

Data I/Os run at ultra-low voltage of 0.6V in the LPDDR4X compared to 1.1V in LPDDR4, having better power efficiency accordingly. 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.

According to IHS Markit, average density in high end smart phones is to be 3.5GB this year and 6.9GB in 2020 with CAGR bigger than 25%. Plus, demand for 8GB mobile DRAM starts to be generated in this year and will occupy the biggest share in the high end smart phones.
