ABSTRACT:
A data output buffer, which includes a data output driver which in turn includes a pull-up circuit (14) operating in response to a first signal and a pull-down circuit (I10) operating in response to a second signal, and a control circuit for sensing a current flowing into the pull-down circuit via a feed-back and controlling the slope of the second signal in accordance with the sensed current. The control circuit includes a sensing circuit (I13) for sensing current flowing into the pull-down circuit upon driving data, and the magnitude of noises generated at the actual ground line (GND.sub.1 +GND.sub.2) due to the current, a voltage adjustment circuit (I14) which operates in response to the output signal of the sensing circuit and thereby adjusts the gate voltage of the pull-down circuit. Thereby, the noises generated in the chip are repressed without affecting the operational speed of the chip.
