20150067242 | INFORMATION PROCESSING DEVICE - In an information processing device, a NAND flash memory has a first area and a second area in each of which a boot code is stored. A processor expands the boot code from the NAND flash memory onto the random access memory, executes the expanded boot code, and rewrites the boot code in the first area and the boot code in the second area at different timings based on the number of times that boot is performed. A boot area setting portion sets access destination of the processor at boot to either the first area or the second area. A controller controls the boot area setting portion so that the access destination of the processor at boot is switched alternately between the first area and the second area at every predetermined number of times that boot is performed. | 03-05-2015 |
