Abstract
An output buffer circuit having adjustable output impedance, including a buffer circuit and a first element which provides a counted value based on a clock signal and outputs the counted value. The output buffer circuit also includes a second element which controls the first element based on an output from the buffer circuit. The control buffer circuit has a third element which receives an input of the counted value and controls the impedance of the buffer circuit based on the counted value. Another embodiment of the output buffer circuit includes a buffer circuit and a first circuit which receives inputs of a reference potential and the potential of an output of the buffer circuit and accordingly controls the buffer circuit so that the potential of the output of the buffer circuit becomes close to the reference potential.
