Abstract

A data output circuit in a semiconductor memory apparatus includes a pre-driver configured to receive input data and then produce a pull-up signal and a pull-down signal, a pull-up driver configured to pull-up drive a first node in response to the pull-up signal and provide an additional pull-up drive when a voltage level on the first node transitions, a pull-down driver configured to pull-down drive a second node in response to the pull-down signal and provide an additional pull-down drive when a voltage level on the second node transitions, and a pad coupled to the first and second nodes to generate output data.
