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
Let me know if there is any another view
