Provided is directed to a data input apparatus and a method of DDR SDRAM which can improve reliability of a circuit operation by transferring data inputted after applying a data strobe signal DQS to an input/output bus GIO by a exact timing, by means of correctly arranging the data strobe signal DQS and a data input strobe pulse dinstbp regardless of time difference of inputting the data strobe signal DQS after a write command, in response to generating a data input strobe pulse dinstbp used to load data to the input/output bus GIO as a data strobe pulse dsp identical to the data strobe signal DQS.
