Semiconductor device having on-die termination structure for reducing current consumption and termination method thereof

PURPOSE: A semiconductor device having an on-die termination structure for reducing current consumption and a termination method thereof are provided to reduce the layout area of a semiconductor device by reducing the number of an on-die termination structure. CONSTITUTION: In a semiconductor device having an on-die termination structure for reducing current consumption and a termination method thereof, a controller(710) controls the number of a terminator to be turned on. An on-die termination unit is turned on in response to an on-die termination control signal. The on-die termination is connected to a data input output pad. The on-die termination has resistance corresponding to N times of external resistance.
