1.Simplicity: SRAMs don't require external refresh 
circuitry or other work in order for them to keep their 
data intact. 
2.Speed: SRAM is faster than DRAM. 
MAin advantage is that
Static RAM is a type of RAM that holds its data without 
external refresh, for as long as power is supplied to the 
circuit. This is contrasted to dynamic RAM (DRAM), which 
must be refreshed many times per second in order to hold 
its data contents. SRAMs are used for specific applications 
within the PC, where their strengths outweigh their 
weaknesses compared to DRAM in terma of speed and sinplicity
