Samsung is always coming up with new ways to be the best at what they do. They recently announced that they have created the first "monolithic" 4 GB LPDDR2 DRAM module to be used in smartphones and tablet PCs. Not only is the DRAM module said to be more power efficient, but it can also transfer data at double the current industry rate--1066 Megabits per second (Mbps).
Currently two chips are in development: an 8 GB chip that stacks two 4 GB chips, giving you 1 GB of RAM and a 16 GB chip that stacks four 4 GB chips, giving you 2 GB of RAM. Both chips are thinner and use less power than the current ones in the market and are based on a 30 nm fabrication process.
