Abstract
A power supply control circuit which can cut off a power supply independently is provided for each column in a memory cell array. The power supply control circuit is controlled by a circuit which is provided for each column and determines whether or not it is necessary to hold information, whereby a power supply for a memory cell which does not need to hold information is cut off.
