Abstract An input buffer circuit which consumes a small amount of power and operates fast is provided. The input buffer circuit includes a differential amplifier for outputting a signal to the output node of the differential amplifier in response to an input signal and a reference voltage, a current sourcing means for reducing the time interval during which the level of the output signal of the differential amplifier increases, and a current sinking means for reducing the time interval during which the level of the output signal of the differential amplifier decreases. The current sourcing means supplies a current to the output node for a predetermined short period of time from the falling edge of the input signal in response to the input signal and the output signal of a buffer. The current sinking means discharges a current to a ground for the predetermined short period of time from the rising edge of the input signal in response to the input signal and the output signal of the buffer.
