A data output circuit of a semiconductor apparatus includes a pull-up driver electrically coupled between a power supply terminal and an output terminal, and configured to drive the output terminal in response to pull-up control signals. The data output circuit may also include a pull-down driver electrically coupled between the output terminal and a ground terminal, and configured to drive the output terminal in response to pull-down control signals. Further, the data output circuit may include a compensation unit configured to open a current path between the output terminal and the ground terminal during an operation period of the pull-up driver, and allow leakage current of the pull-up driver to flow through the current path.
