Samsung's cranking out DDR4 memory

http://www.blogcdn.com/www.engadget....e2_620x340.jpgDDR4 memory is finally in mass production, as Samsung Semiconductor announced it's churning out 4GB 4Gb (512MB) modules, based on "20nm-class" process technology. 32GB sticks like the ones shown above are headed for the premium server market, where Samsung claims their higher speeds (up to 2,667 Mb/s) make for higher performance and 30 percent less power consumption than DDR3. The company claims this is the world's smallest and highest performing 4Gb RAM chip, and we expect it won't stop there -- when Samsung showcased the technology in 2011 it claimed speeds could eventually reach as high as 4Gbps.
Update: It's four gigabits, not gigabytes -- thanks for the corrections, everyone.
