Abstract
In a semiconductor memory device comprising memory cells in which first and second potentials correspond to the logic values "0" and "1", the first potential is closer to the second potential than the potential of unselected word lines, by 0.3 V or more. The pull-up transistor is of the N-type, and the pull-down transistor is of the P-type.
