Abstract
A semiconductor integrated circuit device according to a first aspect of the present invention includes: a first internal power source voltage generating circuit which includes a voltage boosting circuit and a level determining circuit, and outputs a first internal power source voltage, the voltage boosting circuit boosting a voltage based upon a voltage boosting start instruction signal after putting on a power supply, and the level determining circuit which generates a first control signal when an output voltage from the voltage boosting circuit reaches a first level and generates a second control signal for stopping the voltage boosting of the voltage boosting circuit when the output voltage from the voltage boosting circuit reaches a second level higher than the first level; a first control circuit which generates a first action start instruction signal based upon the voltage boosting start instruction signal and the first control signal; and a second internal power source voltage generating circuit which generates a second internal power source voltage based upon the first action start instruction signal.
