Abstract: A voltage monitoring circuit includes an initializing circuit that outputs an initialization signal generated by delaying a power supply voltage as much as a first delay time, a switching circuit that outputs a switching signal in response to a reset signal, a voltage detecting circuit that outputs a detection signal based on the power supply voltage and stops an operation in response to the switching signal, and an output circuit that outputs the reset signal based on the initialization signal and the detection signal.
