PROBLEM TO BE SOLVED: To provide an information processing device, an information processing device control method, and an information processing device control program, which prevent unauthorized use of a memory by a hardware mechanism.SOLUTION: A mark adding unit 131 adds first information, which is generated by causing an error to error detection data of first data that is stored in a first storage area of a memory, to the first data; and adds second information, which is generated by causing an error to error detection information of second data that is stored in a second storage area, to the second data. When the second storage area, out of the first storage area and the second storage area, is allowed to be used, a mark erasure unit 132 erases the second information by rewriting the second information with the error detection information of the second data without rewriting the first information. When data stored in the memory is read, an error detection unit 15 performs error detection processing for the read data by using information which has been added to the read data. |
