Samsung is ready to put 4GB of high-speed RAM into smartphones. The company today announced it has begun production of 8 gigabit, low power double data rate 4 mobile DRAM based on its 20nm processes. The 8Gb LPDDR4 chip allows smartphone vendors to create RAM modules up to 4GB. Some of today's top phones ship with 3GB of RAM, but use slower technology. According to Samsung, the new chip is twice as fast as the previous LPDDR3-based chips and is more power efficient, too. The modules support input/output data rates of up to 3.2Gbps, which is swift enough to support 4K video recording and playback, and continuous shooting of images exceeding 20 megapixels. Samsung said it is already delivering 2GB and 3GB LPDDR4 modules to some phone makers and it expects to deliver 4GB modules beginning early next year.
