SEMICONDUCTOR INTEGRATED CIRCUIT, ELECTRONIC EQUIPMENT, AND METHOD OF CONTROLLING BACK-GATE POTENTIAL OF TRANSISTOR

摘要

PROBLEM TO BE SOLVED: To further reduce the power consumption of a semiconductor integrated circuit and make a faster transition from a standby state to an operating state of the circuit. SOLUTION: The semiconductor integrated circuit comprises a plurality of circuit blocks (20-1, 20-2, ... 20-M) which make a transition from the operating state to the standby state or from the standby state to the operating state, and a master unit (10) which controls a back-gate potential of a transistor in an event-driven manner. The transistor forms the logic elements of the circuit blocks (20-1, 20-2, ... 20-M) based on a finite state machine for previously determining transitions of the states of the plurality of circuit blocks (20-1, 20-2, ... 20-M).
