Abstract
A data driving circuit may include a trigger circuit and a pre-driver. The trigger circuit may be configured to block a remaining signal path among a plurality of signal paths for transmitting data except for a signal path corresponding to a currently selected driving strength. The pre-driver may be configured to drive data, which are transmitted through the signal path corresponding to the currently selected driving strength, using an impedance determined in accordance with a plurality of impedance control codes.
