Abstract
Provided is a driver circuit of a semiconductor apparatus that is capable of operating with improved reliability and consuming less current. The driver circuit comprises a driver configured to generate an internal voltage using a power voltage in response to a control voltage and a controller configured to change the control voltage to a level higher than a level of the power voltage in response to a stand-by mode signal.
Claims17
A driver circuit comprising:
- a controller configured to change a level of a control voltage to any one of levels between a first power voltage and a second power voltage in response to a stand-by mode signal;
- and
- a driver configured to generate an internal voltage using the second power voltage in response to the control voltage,
- wherein the controller includes:
- a dividing resistance block configured to change a level of the control voltage by dividing the first power voltage and the second power voltage by a preset ratio;
- and
- a first switching block configured to electrically couple the first power voltage and the second power voltage to the dividing resistance block when the stand-by mode signal is enabled.
