ABSTRACT:
The internal voltage generator of a semiconductor integrated circuit includes at least one variable reference voltage generating unit that generates a base reference voltage increased or decreased according to the variation in temperature, at least one level shifting unit that transforms the base reference voltage outputted by the at least one variable reference voltage generating unit into at least one prescribed reference voltage for generating internal voltage and outputs the transformed reference voltage, and at least one internal voltage generating unit that generates an internal voltage by using the at least one reference voltage for generating internal voltage outputted by the at least one level shifting unit.
