Abstract:
A semiconductor circuit device having active and standby states and comprising:a logic circuit; said logic circuit including an output node; a first transistor connected between said output node and a first power supply node, turned on/off in response to an input signal in said active state and turned off in said standby state; a second transistor connected between said output node and a second power supply node and turned on/off complementarily to said first transistor in response to said input signal in said active state; and a third transistor connected between said output node and said first transistor, in which said third transistor continuously stays turned on during the period when said first transistor is turned on in said active state and continuously stays turned off in said standby state independent of the input signal, wherein at least one of said first and third transistors has a threshold higher in absolute value than a threshold of said second transistor.
