Abstract
A substrate voltage generating circuit for use in a semiconductor memory device is provided. The semiconductor memory device includes a charge pump for generating a substrate bias voltage in response to a clock signal; a first inverter type detector for detecting whether the substrate bias voltage reaches a target voltage; a second differential amplifier type detector for detecting whether the substrate bias voltage reaches the target voltage; and a driver for generating the clock signal in response to an output of one of the first and second detectors.
