SRAM (Static Random Access Memory) is a type of semiconductor memory. The word "static" indicates that the memory retains its contents as long as power is continuously applied.
In a SRAM, the only time the data on the memory is refreshed or changed is when an actual write command is executed. SRAM is very fast, but is much more expensive than DRAM. SRAM is often used as cache memory due to its speed.
Random access indicates that locations in the memory can be accessed, i.e. written or read, in any order regardless of the memory location that was accessed before.
