Abstract
A negative voltage generation circuit includes a clock generation circuit configured to generate a first clock signal, a first voltage control circuit configured to vary a first resistance value based on a magnitude of a power supply voltage and further configured to control a magnitude of a voltage in a first charge node, based on the varied first resistance value, and a first charge pump circuit configured to charge a voltage, controlled by the first voltage control circuit, in a charge mode, based on the first clock signal, and further configured to output a first voltage, generated by the charging, as a first negative voltage.
