In an information processing apparatus, when an instruction is issued to write back storage contents of a main memory unit that is non-volatile, data and a write destination address included in a backup data that is set with a read permission are extracted from the backup data stored in a backup memory unit that is non-volatile. Further, according to the data and the write destination address extracted from the backup data, the data is written to a storage area of the main-memory unit indicated by the write destination address.
