Beschreibung
Zusammenfassung:	A substrate bias voltage controlling circuit controls the generation of different substrate bias voltages according to specific modes. A first sensing signal generator is controlled by the substrate bias voltage and generates a first sensing signal when the level of the substrate bias voltage is higher than a predetermined first potential level. A second sensing signal generator is controlled by the substrate bias voltage and a specific mode signal and generates a second sensing signal when the level of the substrate bias voltage is higher than a predetermined second potential level and when the mode signal is enabled.
