Abstract
First and second data output circuits obtain corresponding parts of read data of a storage circuit to output to first and second input/output pads in a second test mode. First and second data input circuits obtain output data of the first and second data output circuits via the first and second input/output pads to output in the second test mode. A comparison object selection circuit selects output data of the first and second data input circuits to output in the second test mode. A judging circuit performs a test judgment by comparing output data of the comparison object selection circuit with expected value data and outputs a test result signal in the second test mode.
