SK Hynix today announced it has developed the world's first 128GB DDR4 memory module, twice the capacity of the company's current 64GB module. The new memory module, which is also being touted as the world's highest density module, is based on 8Gbit DDR4 chips created with 20nm process lithography. Hynix's 128GB DDR4 module. The new memory module runs at 2,133Mbps with 64-bit I/O, and processes up to 17GB of data per second. It also runs at ultra low-voltage of 1.2V, compared to 1.35V of existing DDR3 memory modules. While major memory makers such as Hynix, Samsung and Crucial have started producing next-generation DDR4 memory, it's  not expected to show up  in servers until late this year, and in PCs until 2015. Until  Intel  and Advanced Micro Devices begin supporting DDR4 in their processor boards, users won't be able to enjoy the benefits of the technology, which offer twice the performance, twice the base capacity and 20% to 40% less power consumption ...
