Abstract
A data output driver that reduces signal skew includes a data multiplexer which reduces a load of a path through which a pull-up/pull-down control signal is generated by a logic-combination of a data signal. It also decreases the number of bits of a pull-up/pull-down resistance-adjusting code signal, and outputs a data signal in response to high impedance information. Furthermore, a path of an output circuit is simplified through which a pull-up/pull-down control is generated in response to the data signal output from the data multiplexer.
