SEMICONDUCTOR DEVICE FOR DECREASING NOISE OF OUT BUFFER AND METHOD HAVING THE SAME

摘要

A semiconductor device for decreasing noise of an output driver and a method thereof are provided to reduce inter-symbol interference and noise due to reactance component generated in the output driver of the semiconductor device. An output circuit part(120) outputs a first signal and a second signal on the basis of data outputted from a memory cell core block, and the second signal is an inversion signal of the first signal. An output driver block(130) generates a third signal and a fourth signal by differentially amplifying the first signal and the second signal. A control signal generation part(140) generate a control signal of k bits to control the voltage level of a cross-point of the first signal and the second signal on the basis of a reference signal and at least one of the third signal and the fourth signal.
