Abstract
A non-volatile memory device includes a data generation circuit and a reconfiguration processing circuit. The data generation circuit generates: third response data that is different from the first response data (PUF registration mode), when the reconfiguration writing is executed by the reconfiguration processing circuit and the first type of challenge data is obtained again after the reconfiguration writing is executed, after the first response data is generated; and fourth response data that is identical to the second response data (permanent PUF registration mode), when the reconfiguration writing is executed by the reconfiguration processing circuit and the second type of challenge data is obtained again after the reconfiguration writing is executed, after the second response data is generated.
