Samsung Electronics Co. Ltd has pushed out the door what it boasts as the industry's first 3GB low power double data rate 3 (LPDDR3) mobile DRAM, the highest density mobile memory solution for next-generation smartphones. The DRAM uses six of the industry's smallest 20nm class 4Gb LPDDR3 chips, in a symmetrical structure of two sets of three chips stacked in a 0.8mm package. According to the company, the ultra-slim memory solutions will enable thinner smartphone designs and allow for additional battery space, while offering a data transfer speed of up to 2,133Mb/s per pin.

With the increased mobile DRAM capacity, users can enjoy seamless high-quality, Full HD video playback and faster multi-tasking on their smartphones. Also, the LPDDR3 speeds up data downloading and is able to offer full support for LTE Advanced, added the firm.

Samsung's 3GB LPDDR3 DRAM connects with a mobile application processor using two symmetrical data transfer channels, each connected to a 1.5GB storage part. Though asymmetric data flow can cause sharp performance dips at certain settings, the symmetrical structure avoids such issues, while maximising system level performance.

Considering that the current memory storage capacity for PCs is about 4GB, offering 3GB of DRAM memory on mobile devices should help most users enjoy PC-like performance, in narrowing the performance gap between PC and smartphone computing.
