Provided are an apparatus and method for generating an internal voltage adaptively with respect to an external supply voltage. The apparatus includes a class detector and an internal voltage generator. The class detector outputs detection signals indicating a class of a plurality of classes, which correspond to predetermined voltages, to which an input external voltage belongs with respect to a first reference voltage. The internal voltage generator generates and outputs an internal voltage corresponding to the class to which the external voltage belongs as indicated by the detection signals. |
