Abstract
A semiconductor memory device includes an alignment unit configured to align data received from the outside, a plurality of data input/output lines corresponding to the aligned data, respectively and a realignment unit configured to change correspondence between the data and the data input/output lines in response to one or more change signals in a test mode. A method for testing the semiconductor memory device includes inputting data in series using a testing apparatus, aligning the serial data in parallel, and realigning the parallel data in response to one or more change signals.
