An extended sector enable signal (RS_SEL) is a test target control signal for switching the test target between a normal sector and a redundant sector. During a testing of the redundant sector, if a bad redundant sector signal (RSECF) is at a high level (a selected redundant sector is a bad sector), then a forcing signal (FMATCH) is rendered at a high level. In response to the forcing signal (FMATCH) at the high level, a coincidence signal (MATCH) is rendered at a high level by force. Then, the verify operation is skipped for the bad sector. In this way, an address signal that identifies a normal memory block can be utilized for identifying a redundant memory block.
