Abstract
A semiconductor memory device in which data is not written in a transfer destination under a state including an error when an error occurs at the time of reading data at the transfer destination. The semiconductor memory device () comprising a nonvolatile memory () having a data writing unit smaller than a physical block is provided with an error detecting/correcting circuit () in the non-volatile memory (). When data stored in a specified block of the non-volatile memory () is transferred to a different physical block and written, the error detecting/correcting circuit () performs error detection and correction of data.
