Abstract

In order to permit reduced component size without reduction of an external power supply voltage, a semiconductor integrated circuit includes at least three circuits. The first of these three circuits converts the external power source voltage to an internal power source voltage which is smaller than the external power voltage. A second circuit is supplied with the external power source voltage and is responsive to first signals which regulate an operation of the integrated circuit. This second circuit generates second signals which control the integrated circuit so that the integrated circuit performs the desired regulated operation. To carry this out, the second circuit includes at least first transistors which are supplied with the external power source voltage and responsive to the first signals. The second signals generated by the second circuit have amplitudes smaller than those of the first signals. The third circuit is supplied with the internal power source voltage and responsive to the second signals provided by the second circuit to perform the regulated operation. This third circuit includes at least second transistors which are supplied with the internal power source vo…
