摘要：
In a semiconductor integrated circuit device, for realizing high speed, as well as superior product yield rate and usability, while reducing circuit scale and improving on product yield rate and reliability thereof, a main circuit, constructed with CMOS elements, is coupled to a speed monitor circuit for forming a speed signal corresponding to an operating speed thereof and to a substrate bias controller for supplying corresponding substrate bias voltages to the main circuit in response to the speed monitor circuit.
