Used mostly for Cache Memory, Static RAM holds information in memory as long as the power is on. It doesn't have to be constantly refreshed, like standard Dynamic RAM (DRAM). Static RAM is faster than DRAM but it's more expensive and takes up more space.
A memory device in which each cell is formed from four or six transistors configured as a latch or a flip-flop. The term static is used because, once a value has been loaded into an SRAM cell, it will remain unchanged until it is explicitly altered or until power is removed from the device.
A RAM technology whose chips do not require a refresh cycle.(Contrast with DRAM.)
