Abstract:
1. A semiconductor device comprising: a first power line and a second power line, a high voltage generator circuit for supplying a high voltage to said first power line; a current bypass circuit for supplying current to said second power line from the first power line until the voltage difference between said power lines reaches a first target value; a first PMOS transistor coupled between said first power line and said second power line, said PMOS transistor operating in response to a PMOS drive current; and a controller for controlling said PMOS drive current in response to the voltage on said second power line, whereby said current bypass circuit is cut off when said high voltage reaches said target first value, and current is supplied to said second power line through said PMOS transistor until the voltage on said second power line reaches a second target voltage lower than said first target voltage.
