Abstract:
A semiconductor device in related art has a problem that security on confidential information stored is insufficient. A semiconductor device of the present invention has a unique code which is unique to a device and generates unique code corresponding information from the unique code. The semiconductor device has a memory region in which specific information obtained by encrypting confidential information is stored in a region associated with the unique code corresponding information. The specific information read from the memory region is encrypted with the unique code corresponding information to generate the confidential information.
