Abstract
An internal voltage generating circuit includes a first voltage application unit, a second voltage application unit, a first regulator, a second regulator, and a controller. The first and second voltage application units respectively provide a first voltage and a second voltage. The controller generates a bulk voltage, a first control signal, and a second control signal from the first and second voltages. The first regulator is enabled or disabled according to the first control signal and generates and outputs the first internal voltage based on the bulk voltage, the first voltage, and a first reference voltage. The second regulator is enabled or disabled according to the second control signal and generates and outputs the second internal voltage based on the bulk voltage, the second voltage, and a second reference voltage.
