A semiconductor integrated circuit includes a DLL circuit generating an internal clock signal, a plurality of clock generators generating respective output clock signals based on the internal clock signal, a plurality of output buffers outputting to a plurality of data input/output pins data according to corresponding output clock signals respectively, and a selection circuit. The selection circuit outputs a code signal for allowing the timing of the earliest output clock signal to conform to the timing of the latest output clock signal. A predetermined clock generator adjusts the timing of the output clock signal according to the code signal.
