A semiconductor device is designed to provide an access control for a memory that includes a plurality of storage regions storing the same boot programs comprised of a set of program data. The semiconductor device is provided with a memory controller for reading out the program data from the storage regions, and an error detection circuit performing error detection on the program data read out. When the error detection circuit detects an error in one of the program data read out from one of the storage regions, the memory controller reads out the corresponding one of the program data from another of the storage regions.
