Abstract
A data output buffer circuit for rapidly outputting data read from a memory cell of a semiconductor integrated circuit to an external circuitry without generating noise of a high voltage level caused by variation of a voltage includes an input terminal for receiving data, a first current path being connected between a first power supply voltage and an output terminal to be open and closed by the data from the input terminal; a second current path being coupled between a second power supply voltage and the output terminal to be complementarily open and closed by the data from the input terminal, and power supply voltage detector for detecting a potential difference between the first and second power supply voltages, and adjusting the sizes of the first and second current paths in accordance with the detected potential difference to generate an output data with a constant current.
