ABSTRACT:
Semiconductor integrated circuits, and more particularly an internal power-supply voltage supplier, can be adapted to high density memory devices, for providing a converted external power-supply voltage as an internal power-supply voltage having a desired potential. An internal power-supply voltage supplier receives a reference signal and an internal power-supply voltage signal and provides a semiconductor integrated circuit with an internal power-supply voltage having a desired voltage level by way of a driver, and comprises an offset generator connected to the driver, including two transistors having different width-length characteristics, for receiving the reference signal and the internal power-supply voltage signal and producing an offset corresponding to the received signals, the internal power-supply voltage is provided at a desired voltage level by the driver when the offset generator performs an offset operation.
