List three differences between Dynamic RAM and Static RAM. 3m Jun2008
Static RAM
ü SRAM uses transistor to store a single bit of data
ü SRAM does not need periodic refreshment to maintain data
ü SRAM’s structure is complex than DRAM
ü SRAM are expensive as compared to DRAM
ü SRAM are faster than DRAM
ü SRAM are used in Cache memory
Dynamic RAM
ü DRAM uses a separate capacitor to store each bit of data
ü DRAM needs periodic refreshment to maintain the charge in the capacitors for data
ü DRAM’s structure is simplex than SRAM
ü DRAM’s are less expensive as compared to SRAM
ü DRAM’s are slower than SRAM
ü DRAM are used in Main memory
