ABSTRACT:
Provided is directed to an internal supply voltage driver control circuit which can vary a driver size by way of selecting a driver control signal by using a fuse cutout, and also decide an internal voltage by using fuses, by means of including: a plurality of drivers for outputting an internal voltage in response to a plurality of enable signals; and a control unit for selectively outputting one of the plurality of enable signals according to a combination of a test mode entry signal and a plurality of address signals, and then deciding a selected enable signal according to the fuse cutout.
