Abstract

PURPOSE:To reduce power consumption by reducing the mean amount of a current by adding MISFETs to a logical block. CONSTITUTION:A deletion type MISFETQl1 wherein a current flows between its source and drain even if no bias voltage is applied between its gate and source is used as a load transistor (TR), and enhancement type MISFETs Qd1-Qd3 wherein currents flow between their sources and drains when bias voltages are applied are used as driving TRs; and an MISFETQd4 applied with a clock pulse phi at its gate electrode is added, and the FETs Ql1 and Qd4 and a logical block LB are connected in series, so that an output signal appears at the connection point of the block LB and FETQl1. Then, only when the FETQd4 turns on by the clock pulse phi, a current flows through the series closed loop of the FETs Ql1 and Qd4, and the block LB, and the current does not flow normally, reducing power consumption.
