PURPOSE: An output driver of a semiconductor device is provided to reduce mismatch generated in a pull-up and pull down path by controlling the pull-up and pull-down simultaneously. CONSTITUTION: A data Input unit(210) generates a driving signal. The level of the driving signal changes according to a logic level. A plurality of pull-up drivers(230) pull-ups a data output terminal using different resistance. A plurality of pull-down drivers(240) pulls down the data output terminal using different resistance. A mode controller(220) receives resistance setting information and mode information. The mode controller controls the operation of the pull-down driver and pull-up driver. |
