==Original Abstract Submitted==

Disclosed is a charge pump of a flash memory, which includes a first stage pump that is connected between an output terminal and a first pump node, and a second stage pump that is connected between the first pump node and a second pump node. The first stage pump includes a first switch circuit that is connected between a power terminal and the first pump node and provides a power supply voltage to the first pump node in response to a first stage signal, in a normal operation, and a first pump circuit that generates a first pumping voltage by using a voltage of the first pump node in response to a first clock signal and provides the first pumping voltage to the output terminal. The first switch circuit blocks a current flow from the first pump node to the power terminal in a sudden power-off event.
