SRAM is RAM that retains data bits in its memory as long as power is being supplied. Unlike DRAM, which stores bits in cells consisting of a capacitor and a transistor, SRAM does not have to be periodically refreshed. Static RAM provides faster access to data and is more expensive than DRAM.
SRAM is used for a computer's cache memory and as part of the random access memory digital-to-analog converter on a video card.
