PROBLEM TO BE SOLVED: To provide an information processing device, a data transfer control method, and a data transfer control program which, while maintaining performance and resource usage efficiency, secures system reliability.SOLUTION: An address translation table 18 stores correspondence between a logical address and a physical address, as well as change information indicating a change in the correspondence, when the correspondence is changed so that the physical address corresponding to a logical address now corresponds to another logical address, and the other logical address. A table control unit 14 changes, upon receiving from a CPU an instruction for transferring data between the logical addresses, the correspondence in the address translation table 18 so that the logical address at the destination of transfer corresponds to the physical address in which the data is stored, sets change information for the logical address at the source of transfer, and causes the logical address at the destination of transfer to be stored as another logical address corresponding to the logical address at the source of transfer. |
