Using its 20 nanometer-class manufacturing process, Samsung's new 12Gbit DRAM dies will offer “a 50 percent greater density than existing 8GB dies, allowing manufacturers to offer mobile devices with more RAM than a mainstream laptop; 6GB, with four 12Gbit dies in a single DRAM chip package”, says Ars Technica. Speeds will be 30 percent faster (topping 4,266 Mbps) than its previous 8Gbit LPDDR4, also consuming 20 percent less power, according to Samsung.
Finally, this new process has potential for more than just smartphones and tablets, as Samsung hopes to see its new 6GB DRAM in ultra-slim PCs, as well as digital appliances and IoT devices. As far as a time frame goes, Samsung has been diligently finishing up manufacturing these chips in time to be featured in (hopefully) many of next year's mobile devices.
