It is used for cache memory.
Further Explanation:
Cache memory is the memory that stores the instructions and data that is used repeatedly. If the processor wants some data it first looks into cache memory then the processor doesn't has to look into the main memory for the data or instructions which is more time consuming. As the SRAM uses small but a constant source of power, it is usually used for making cache memories. Moreover it is benficial to keep the previously used data in SRAM(Which is faster) than acessing DRAM (Which is way more slow than SRAM.
