Abstract
A semiconductor device includes a constant voltage generation circuit generating a constant voltage commonly to reference voltages corresponding to a plurality of internal voltages. The plurality of reference voltages are generated from the common constant voltage. Thus, the semiconductor device for generating internal voltages is implemented, which allows reduction in layout area and decrease in test time for voltage adjustment.
