Question

Compare and contrast the following technologies (SRAM and DRAM)

Answer 1

DRAM (Dynamic Random Acess Memory) =>
(1) It stores data temporarily as the data is lost when power supply is suspended.
(2) It needs to be refreshed periodically in order to retain data.
(3) It is slower than SRAM.

SRAM (Static Random Acess Memory) =>
(1) It loses data when turned off.
(2) It doesn't need to be refreshed like DRAM to retain information.
(3) It is fast and expensive.
