SRAM vs DRAM

 SRAM (static random access memory) and DRAM (dynamic random access memory) are both types of random access memory (RAM) in computers. SRAM is faster and more expensive, while DRAM is slower and more affordable. 

	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
