1. An information processing device comprising: a processor; an address generation section that generates a write address indicating a write position in a nonvolatile memory in a write operation, write addresses generated by the address generation section being sequential; an order generation section that generates order information in the write operation, the order information indicating an order of the write operation; and a write control section that writes write-data to the write position of the nonvolatile memory indicated by the write address generated by the address generation section, and writes the order information related to the write-data to the nonvolatile memory.
