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.

Difference between static and dynamic RAM?
Dynamic RAM:-Dram stores the data in the form of charge
into capacitor.for storing another charge capacitor require
to refresh the data which it holds.This refresh operation
is where dynamic RAM gets its name.
Static RAM:-is a type of semiconductor memory where the
word static indicates that, unlike dynamic RAM (DRAM), it
does not need to be periodically refreshed, as SRAM uses
bistable latching circuitry to store each bit.
