Abstract
A power-up signal generation circuit includes a discharge driving unit configured to discharge a voltage of a power-up detection node in response to a voltage of an external power supply voltage, a charge driving unit configured to charge the voltage of the power-up detection node in response to a voltage of an internal power supply voltage, a power reset discharging unit configured to discharge a voltage of the power-up detection node while the semiconductor integrated circuit is reset, and an output unit configured to output a power-up signal in response to a voltage change of the power-up detection node.
