Zip Drive Interview Question:

Explain Difference between static and dynamic RAM?

Submitted by: Administrator

Static RAM:
No refreshing, 6 to 8 MOS transistors are required to form one memory cell, Information stored as voltage level in a flip flop.

Dynamic RAM:
Refreshed periodically, 3 to 4 transistors are required to form one memory cell, Information is stored as a charge in the gate to substrate capacitance.
