Abstract:
A driver circuit includes unit slice circuits that generate an output data signal based on an input data signal. The driver circuit reduces a voltage swing of the output data signal without changing a termination resistance of the driver circuit in response to decreasing a number of the unit slice circuits that generate the output data signal based on the input data signal.
