Patent ID: 7746161

Claim:
A semiconductor integrated circuit device, comprising: a first voltage generating circuit that is driven at a time of power-on setup, the first voltage generating circuit outputting a first output voltage transiting from a ground voltage potential to a first voltage potential lower than the ground voltage potential, the first voltage generating circuit finally maintaining the first output voltage having the first voltage potential, at a first output terminal; a second voltage generating circuit which outputs a second output voltage transiting from the ground voltage potential to a second voltage potential lower than the ground voltage potential and higher than the first voltage potential, the second voltage generating circuit finally maintaining the second output voltage having the second voltage potential, at a second output terminal; a first coupling capacitance which exists between the first output terminal and the second output terminal; and a current supplying circuit which supplies a current to the second output terminal of said second voltage generating circuit so as to reduce an electric potential of the second output terminal toward the ground voltage.
