Abstract
The semiconductor memory device includes an internal refresh circuit and an input circuit composed of first and second transistors of a different conductivity type having gates connected in common to an external control signal input terminal and connected in series with each other. A third transistor is connected in series to the first and second transistors. The third transistor is deactivated when the internal refresh circuit, operates to carry out a self-refresh mode, thereby suppressing a power consumption in the input circuit.
