SRAM

Static RAM

Static RAM is physically different to dynamic RAM as the memory contents do not have to be continually refreshed. This means that it can always be accessed and so SRAM is a faster type of memory. However the process of manufacturing the memory and the components used make it more expensive. For this reason SRAM is used in smaller quantities where fast memory is required, such as cache.

SRAM is fast but expensive and is typically used for cache memory.
