Abstract

A mode switching transistor which is controlled by a chip enable signal is connected between a power supply terminal and a MOS inverter including transistors. The transistor functions as a weak depletion or depletion type MOS transistor to provide sufficient current with a first back gate bias given in an active mode and functions as a perfect enhancement type transistor to completely cut off current with a second back gate bias given in a standby mode.
