ABSTRACT:
In an output driver circuit and method, a control circuit generates a control signal in response to a current internal data signal. An output driver generates an output data signal in response to the control signal. A pre-emphasis circuit adjusts a current flowing through a node having the control signal generated thereon in response to a previous internal data signal. The pre-emphasis circuit may also adjust the output signal in response to the previous internal data signal.
