A semiconductor integrated circuit includes: a elevated voltage detector that outputs a elevated voltage pump enable signal; a elevated voltage pump that is driven by the elevated voltage pump enable signal to pump the elevated voltage; a substrate bias voltage detector that outputs a substrate bias voltage control signal when at least one of the elevated voltage pump enable signal and a substrate bias voltage pump enable signal for driving a substrate bias voltage pump changes to an active state; and the substrate bias voltage pump that is driven by the substrate bias voltage control signal to pump the substrate bias voltage.
