Abstract
A logic circuit which is driven at low voltage and operates at high speed and low power consumption is provided. Substrate potentials of P and N type transistors MP,and MN,constituting an inverter are controlled correspondingly to a stable state of the inverter. In a stable state of the inverter in which the P type transistor MP,is ON, the substrate potential of the N type transistor MN,which is OFF is lowered to ground potential or lower and, in a stable state of the inverter in which the N type transistor MN,is ON, the substrate potential of the P type transistor MP,which is OFF is raised to a power source potential or higher.
