Question
Advantage of SRAM over DRAM   ?
 Question Submitted By :: Operating-Systems-General-Concepts
I also faced this Question!!     Answer Posted By  
 
Answer
# 1
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

Simplicity: SRAMs don't require external refresh circuitry
or other work in order for them to keep their data intact.
Speed: SRAM is faster than DRAM.
In contrast, SRAMs have the following weaknesses, compared
to DRAMs:
Cost: SRAM is, byte for byte, several times more expensive
than DRAM.
Size: SRAMs take up much more space than DRAMs (which is
part of why the cost is higher).

Answer
# 3
sRAM is static RAM and the DRAM is the dynamic RAM

when the power is off the information will be kept upto
some time in SRAM and will be erased quickly.

SRAM is High Cost and DRAM is less cost

Answer
# 4
SRAM does not have a capacitor to store data.
In SRAM the data is lost when the memory is not electrically
powered
SRAM is faster and reliable than DRAM

Answer
# 5
1)SRAM does not require refreshing while DRAM requires.
2)SRAM is faster than DRAM.
3)In SRAM modules are simple while in DRAM modules are complex
4)SRAM use low power than DRAM.
5)SRAM used in cache memory while DRAM used in main memory.
