Abstract
A data output buffer includes a data driving circuit having a pull-up transistor responsive to a first signal and a pull-down transistor responsive to a second signal, a first control circuit for regulating the slope of the first signal to be less steep after reaching the threshold of the pull-up transistor than before reaching the threshold of the pull-up transistor, and a second control circuit for regulating the slope of the second signal to be less steep after reaching the threshold of the pull-down transistor than before reaching the threshold of the pull-down transistor. As a result, noise generated by the transition of the output signal of the data output buffer is reduced without affecting operation speed.
