Abstract
A semiconductor device includes a data output selection circuit suitable for outputting first pattern data as selection data in the case where a training operation is performed, outputting information data as the selection data in the case where a mode register read operation is performed, and outputting second pattern data in the case where the training operation is performed; and a data pad circuit including a first data pad and a second data pad, wherein the first data pad outputs the selection data and the second data pad outputs the second pattern data.
