More RAM for your phones: Samsung announces 8Gb LPDDR5 DRAM

Samsung unveils 8 gigabin LPDDR5 RAM chips for next-gen phones

While Samsung is already pushing for LPDDR5 mass production, JEDEC itself did not finalize the full specifications for DDR5 and LPDDR5, but this should occur later this year.

Samsung today announced that it has developed the industry's first 10-nanometer class 8GB LPDDR5 DRAM which can be used in mobile devices.

Samsung will offer the new chip in two bandwidths - 6,400 Mb/s at a 1.1 operating voltage (V) and 5,500 Mb/s at 1.05V. This performance advancement has been made possible through several architectural enhancements.

In terms of power savings, the 10nm-class LPDDR5 has been engineered to lower its voltage in accordance with the operating speed of the corresponding application processor when in active mode to maximize power savings. Additionally, it doesn't overwrite cells with "0" values. Its deep sleep mode needs about half as much power as LPDDR4X, so a 30% power saving in general usage is to be expected. 'We will continue to expand our next-generation 10nm-class DRAM lineup as we accelerate the move toward greater use of premium memory across the global landscape.

Due to take over from DDR4 and offering, as with each successive generation of the Double Data Rate (DDR) memory standard, improved performance, Samsung's new LPDDR5 product is aimed to low-power yet high-performance devices including smartphones, tablets, and embedded systems of the type you might find in self-driving vehicles. This new 10nm class 8Gb LPDDR5 DRAM will be useful to support the upcoming 5G networks, and AI-powered mobile applications as well. The chip will be capable of powering artificial intelligence and machine learning applications. Nearly all high-end phones, mobile devices, and even portable PCs these days use LPDDR4X or even just LPDDR4.
