    • A semiconductor memory device for inputting/outputting high speed data is provided to prevent distortion of data due to delay or skew generated in an input/output process of data by selectively outputting a preamble data pattern to data. A first serialization part(100A) serializes parallel inputted eight data, and outputs successive four data.

A second serialization part(100B) receives an output of the first serialization part, and outputs successive two data. A third serialization part(100C) receives an output of the second serialization part, and outputs the serialized data. Each data window of the data outputted in the first serialization part is four times of each window of the serialized data. A phase moving part moves a phase of the four data among the eight data as four times of each data window of the serialized data after the preamble data is outputted according to the operation mode.
