LPDDR3 (via Samsung)
Future mobile devices running 4G will be getting a boost in memory performance if they incorporate Samsung’s new LPDDR3 modules (Low Power Double Data Rate). The company recently announced their mass production of the JEDEC standard LPDDR3 modules, only ten months after their previous iteration of their slower LPDDR2 memory. The new 30nm mobile memory clocks in at 1600 MHz per pin with a data transfer rate of 12.6GB per second making the modules 50% faster over the previous LPDDR2 chips (which have a data transfer rate of 8.5GB per second). To save space, and improve on performance, the company stacked 4 of the modules on top of each other to create a 2GB module that will be able to fit in mobile devices that are increasingly becoming thinner. The chips also utilize some new technology such as write-leveling and CA (Command/Address) training (compensates for signal skew between the SoC and DRAM), low I/O capacitance and ODT (Optional On-Die Termination). Samsung states that the chips will enable users to watch full HD video (on 4 inch screens) in real-time as opposed to downloading the content beforehand. The company expects to see their LPDDR3 modules in mobile devices at around the second half of 2013.
