Samsung now producing 4-gigabit 20nm DDR2 memory, aims to bring 2GB to smartphones without increased power usage

If you weren’t already convinced that the 2GB RAM smartphone evolution is upon us, look no further than this announcement from Samsung today. According to the Korean giant, they are now mass-producing 4-gigabit quantities of LPDDR2 memory built on a 20nm manufacturing process. This means that 2GB of DDR2 memory will become cheap enough for OEMs to install in their high-end smartphones en masse.

The chips are 20 percent thinner than the previous 30nm parts, making four stacks of 512MB chips a viable alternative to the larger and denser chips of yesteryear. These chips boast speeds of 1066Mbps without increasing power usage, meaning that devices such as the LG Optimus LTE 2 and Japan’s Samsung Galaxy S III will not draw any more power from the motherboard than their 1GB international cousins.

According to Samsung, the new 20nm parts will account for “approximately 13 percent of total DRAM shipments in 2012, 49 percent in 2013 and 63 percent in 2014, with 4Gb DRAM becoming the mainstream chip in the DRAM market around the end of 2013.”
