Abstract
An internal circuit has a plurality of circuit blocks operating by receiving an internal power supply voltage. An internal voltage control circuit generates a plurality of regulator control signals according to a combination of operating circuit blocks. A plurality of regulators operate in response to activation of the regulator control signals respectively to generate the internal power supply voltage by using an external power supply voltage. For example, as the number of the operating circuit blocks increases, the number of the operating regulators increases. By thus generating the regulator control signals according to the actual operation of the internal circuit to control the operations of the regulators, it is possible to reduce variation in the internal power supply voltage to a minimum. As a result, an operating margin of a semiconductor integrated circuit can be improved and a yield of the semiconductor integrated circuit can be improved.
