Differences between DRAM and SRAM?

Answer Posted / rajan

SRAM (Static RAM)
*stores data till the power is switched off
Uses a set of transistors for each memory cell

*Does not refresh the memory cell after each
reading of the transistors.

DRAM (Dynamic RAM)
*stores data only for few milliseconds
Uses a single transistor and capacitor
for each memory cell

*Needs to refresh the memory cell after each
reading of the capacitor.
