Abstract:
A semiconductor memory device includes a first data input/output unit configured to receive a normal training data, whose data window is scanned based on an edge of a source clock, in response to a training input command, and output a data in a state where an edge of the data window is synchronized with the edge of the source clock in response to a training output command, and a second data input/output unit configured to receive a recovery information training data, whose data window is scanned based on the edge of the source clock, in response to the training input command, and output a data in a state where an edge of a data window is synchronized with the edge of the source clock in response to the training output command.
