A steady technique of data storage is used by SRAMs, and the data is kept consistent as long as electricity is provided to the memory device. This contrasts with DRAM (dynamic RAM), which actively saves data and requires frequent refreshing of the data in the memory. SRAM uses less electricity and is quicker than Memory because it saves data statically.

SRAM, however, has a higher manufacturing cost than DDR because it uses a more intricate structure. SRAM chips cannot contain as much data as DRAM chips due to this complexity's limitations on the quantity of data that a single chip can keep. DDR is therefore most frequently used as the primary memory in desktop devices. SRAM, however, is frequently utilized in lesser applications, like hard drive caches and Processor cache memory. Other household devices, ranging from big machines to little kids' games, also use it.

It's crucial to distinguish between SRAM and SDRAM, a variety of DRAM.
