PURPOSE: A counter of a semiconductor device is provided to stably output a data by improving a data skew. CONSTITUTION: A 2 bit counter(300) includes a first counter block(310) and a second counter block(320). The first counter block includes a D flip-flop(311), a second MUX(315), a first MUX(313), an output part(317), and a first MUX control part(319). The second counter block includes a D flip-flop(321), a second MUX(325), a first MUX(323), an output part(327), and a first MUX control part(329). The D flip-flop outputs a first output signal and a second output signal. The second MUX selectively outputs the second output signal of the D flip-flop and an external data according to a data load signal. The first MUX delivers one of the output signal of the second MUX and the first output signal of the D flip-flop to an input signal of the D flip-flop according to the data load signal or a counter enable signal.
