DIFFERENCE BETWEEN SRAM AND DRAM?

RAM IS OF TWO TYPES , BOTH IS USED TO STORE THE DATA ,BUT THE WAY IT STORES THE DATA IS DIFFERENT.
          DYNAMIC RAM NEEDS TO BE FREQUENTLY REFRESHED  TO HOLD THE DATA
AND STATIC RAM HOLDS OR RETAINS THE DATA AS LONG AS POWER IS NOT OFF.THIS IS THE MAJOR DIFFERENCE BETWEEN THEM.
        THE DIFFERENCE BETWEEN THEM IS:
SRAM IS FASTER
SRAM IS CHEAPER
SRAM REQUIRES 6 TRANSISTORS TO STORE BIT OF DATA
SRAM IS COMMONLY USED IN CACHE MEMORY AND DRAM IN MAIN MEMORY
SRAM REQUIRES LESS POWER.
