ABSTRACT:
A power-up signal generation circuit includes a first power-up detecting unit, to which an external power supply voltage is applied, for activating a first power-up signal when an increase of the external power supply voltage is detected, a second power-up detecting unit, to which an internal power supply voltage is applied, for activating a second power-up signal when an increase of the internal power supply voltage is detected and a power-up signal generating unit for activating a final power-up signal in response to combination of the first and the second power-up signals.
