ABSTRACT:
A semiconductor memory device having a first memory block used when it is determined to be used in a first case, a second memory block used as an alternative of the first memory blocks when it is determined to be used in a second case, a write section that writes determination data into the first memory block for making a determination at the time of the determination and writes the determination data into the second memory block and a read section that reads the determination data written into the first memory block by the write section for making a determination at the time of the determination and reads the determination data written into the second memory block by the write section.
