SRAM vs DRAM

Static RAM(SRAM) and Dynamic RAM(DRAM) are both types of volatile memory used in computers, but they differ significantly in how they store data, speed, cost and power consumption. SRAM uses flip flops to store data and retains it as long as the other hand, stores data as a charge on capacitors and requires periodic refreshing to maintain data, making it slower and less expensive but also more power efficient.

 

	SRAM	DRAM
Data retention	Retains data as long as power is supplied	Requires periodic refreshing to retain data
Speed	Faster access time	Slower access time
Power consumption	Consumes less power	Consumes more power
Use	Cache memory, CPU registers	Main memory, system memory, storage
