Abstract
A semiconductor memory device that may include output drivers, each of which varies a data swing width in response to a correction code, and one or more data swing width control portions. Each of the data swing width control portions may correspond to an output driver, may vary the correction code according to a data swing width of the corresponding output driver to change the data swing width to a correction swing width, and then varies the correction code again to the extent that data of the corresponding output driver are normally transmitted, which may reduce the data swing width.
