Abstract: A semiconductor device in related art has a problem that security at the time of writing data cannot be sufficiently assured. A semiconductor device of the present invention has: a unique code generating unit generating an initial unique code which is a value unique to a device and includes an error in a random bit; a first error correcting unit correcting an error in the initial unique code to generate an intermediate unique code; a second error correcting unit correcting an error in the intermediate unique code to generate a first determinate unique code; and a decrypting unit decrypting, with the first determinate unique code, transmission data obtained by encrypting confidential information with key information generated on the basis of the intermediate unique code by an external device to generate confidential information.

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.
