Samsung today claimed to be the first with a 32GB DDR3 RAM stick. The record device comes by using a 50 nanometer manufacturing process to produce 16 gigabit (2GB) stacked memory chips, nine of which are put on each side of the stick to provide the 32GB plus a certain degree of overhead. Despite the sheer amount of memory, Samsung is keen to observe that the 1.35V example uses about 20 percent less power than previous memory, which normally uses 1.5V of energy.
The specific module is intended for servers, where long RAM sticks and very high memory counts are feasible; pricing isn't public but will be very high. However, the technology behind the memory means it can also increase densities for smaller components. 16GB DDR3 should be possible for regular desktop memory, and 8GB is likely for notebooks.
