Samsung is preparing 6GB memory chips for flagship smartphones and tablets. Samsung today announced it has begun production of 12-gigabit, low power double data rate 4 mobile DRAM based on its 20nm processes. The 12Gb LPDDR4 chip follows the same path set by Samsung's 8Gb module, announced last year. It allows smartphone vendors to create RAM modules up to 6GB by pairing two together. Today's flagships include up to 4GB of RAM, though many still ship with 3GB. According to Samsung, the new 12Gb chip is 30% faster than the previous 8Gb LPDDR4 chip and is 20% more power efficient. The module supports input/output data rates of up to 4.26Gbps, which is swift enough to support 4K video recording and playback, and continuous shooting of images exceeding 20 megapixels. Samsung said it expects to deliver 6GB modules to phone makers in the near future.
