The 8Gb LPDDR4 mobile DRAM would allow for faster applications, higher resolution displays, longer battery life, and more advanced features for your device. With the new Low Voltage Swing Terminated Logic (LVSTL) I/O interface, data will be transferred per pin at a rate of 3200Mbps. That is twice as fast as the 20nm process LPDDR3 DRAM that is currently mass produced. It also achieves 50% higher performance than the fastest DDR3 memory chip and at 1.1 volts, uses only 40% of the energy.
The chip will be used for top-shelf devices, including smartphones, and will be ready for shipment in 2014.
