Patent ID: 7508252

Claim:
A semiconductor integrated circuit device comprising: a boosted-voltage power-supply circuit configured to generate a boosted voltage; an internal circuit that is driven by the boosted voltage; a reduced-voltage power-supply circuit configured to reduce the boosted voltage and output a reduced voltage; and a control circuit configured to receive the reduced voltage and control the internal circuit by the received reduced voltage, wherein said boosted-voltage power-supply circuit comprises: a first output terminal for the internal circuit; a second output terminal for the control circuit; and an output voltage control section that outputs the boosted voltage to the internal circuit through a first line from the first output terminal and outputs the boosted voltage to the reduced-voltage power-supply circuit from the second output terminal through a second line that is different from the first line, wherein said output voltage control section outputs the boosted voltage to said reduced-voltage power-supply circuit before outputting the boosted voltage to said internal circuit by a switching operation.
