Abstract
A precharge control circuit includes a precharge voltage supply unit for generating a precharge voltage according to a voltage level of a precharge control signal, a voltage generator for generating an operating voltage for controlling the voltage level of the precharge control signal in response to a first enable signal and a voltage control signal, and a signal generator for fixing the precharge control signal to a specific voltage level in response to a second enable signal and for linearly changing the voltage level of the precharge control signal according to a slope, determined by a level of the operating voltage, when the second enable signal is disabled.
