Abstract
A data output device may include a driving control, a voltage supply unit, and an output driving unit. The driving control unit outputs a pull-up control signal and a pull-down control signal in response to a logic value of data when an output enable signal is activated. The voltage supply unit generates a driving voltage lower than a supply voltage. The output driving unit is driven in response to the driving voltage, and controls an amplitude and a slew rate of a voltage supplied to a global line according to the pull-up control signal and the pull-down control signal.
