PURPOSE: A voltage boosting circuit of a semiconductor device is provided to generates a voltage over a power-supply voltage, and prevents a sudden increasing of a signal line's potential. CONSTITUTION: A voltage boosting circuit includes a voltage detector for detecting a potential of a boosted signal line in active mode. The voltage detector includes a compensation current provider. The compensation current provider is connected to an input terminal of a discriminator having a logic threshold voltage level, and is connected to a power-supply voltage. If an input potential of the discriminator becomes lowered because of a power-supply voltage variation, the compensation current provider inputs a compensation current to an input terminal of the discriminator. The compensation current is proportional to a power-supply voltage variation. Accordingly, a potential of the signal line driven by the voltage boosting circuit is not suddenly increased.
