Voltage booster circuit, semiconductor device, and voltage booster circuit control method

摘要

A voltage booster circuit includes a reference voltage generation circuit that generates a first potential and supplies the first potential to a first potential line; a booster section that supplies a second potential to a second potential line, the second potential being boosted from the first potential; a booster control section, connected to the second potential line, that controls the booster section in accordance with the second potential; a switch connected to the first potential line and the second potential line; and a control circuit that controls the switch in accordance with a potential difference between the first potential and the second potential.
