ABSTRACT:
There is provided a power up circuit capable of outputting a power up signal delayed by a predetermined time. The power up circuit includes a voltage divider for dividing an external voltage, a delay controller for generating a control signal to control an output voltage of the voltage divider for a predetermined time by using the external voltage, and a signal generator for generating a power up signal delayed by a predetermined time by using the control signal.
