Abstract
An electronic device includes an internal voltage driving circuit configured to drive an internal voltage to one of first and second power supply voltages based on a driving control signal depending on an operating frequency. The electronic device includes a driving control signal generation circuit configured to generate the driving control signal that sets a level of the internal voltage, by detecting the level of the internal voltage.
Claims20
An electronic device comprising:
- an internal voltage driving circuit configured to drive an internal voltage to one of first and second power supply voltages based on a driving control signal and a mode signal depending on an operating frequency;
- and
- a driving control signal generation circuit configured to generate the driving control signal that sets a level of the internal voltage by detecting the level of the internal voltage, wherein the mode signal is generated from setting code set as information with regard to the operating frequency when a mode register set operation is performed.
An electronic device comprising:
- a switching control signal generation circuit configured to output a driving control signal as one of first and second switching control signals depending on an operating frequency based on a mode signal;
- and
- a power switching circuit configured to drive an internal voltage to one of first and second power supply voltages based on the first and second switching control signals, a level of the driving control signal being adjusted depending on a level of the internal voltage, wherein the mode signal is generated from setting code set as information with regard to the operating frequency when a mode register set operation is performed.
