Abstract
When an operational mode is shifted to a standby mode, a first transistor is brought into a conduction state by a control signal, and a word line is thereby clamped to a ground voltage. Further, a second transistor is brought into a non-conduction state, and supply of an internal power supply voltage to a word line driver is shut off. Subsequently, the supply of the internal power supply voltage is halted for saving electrical power. When the operational mode returns to a normal mode, the supply of the internal power supply voltage is started, and subsequently, the first transistor is brought into the non-conduction state by the control signal, and the second transistor is thereby brought into the conduction state.
