Abstract

A body bias control system allows for independent design of a functional module, thereby reducing the burden of designing the module. The body bias control system provides a switch circuit having an area in which the body bias is controlled independently of its outside portion, for controlling the supply of body bias in the vicinity of the area. Preferably three types of switches are provided for switching the body bias to suitable levels for a standby mode, a mode of normal operation and a mode of high-speed operation.
