ABSTRACT:
A precharge voltage supply circuit and a semiconductor device using the same are disclosed. The semiconductor device includes a first comparator for comparing a precharge voltage with a first reference voltage having a first voltage level and outputting a first compare signal as a result of the comparison, a second comparator for comparing the precharge voltage with a second reference voltage having a second voltage level and outputting a second compare signal as a result of the comparison, a decoder configured to receive and decode the first compare signal and the second compare signal and output a plurality of control signals as a result of the decoding, and a precharge voltage supply circuit configured to receive the plurality of control signals and supply the precharge voltage.
