ABSTRACT:
An output driver of a semiconductor device, removing the inter-symbol interference noise in data transmission in order to achieve a signal integrity, includes a main driver for driving an output terminal and a supporting driver for controlling the inter-symbol interference noise. The supporting driver is provided with a pull up supporting driver for pulling up the output terminal by detecting a transmission pattern of an output data and a pull down supporting driver for pulling down the output terminal by detecting the transmission pattern of the output data.
