PROBLEM TO BE SOLVED: To reduce the occurrence probability of a soft error in a cache.SOLUTION: An information processing device 1 includes a processor 4, a memory 2, and a cache 3. The cache stores information that is read from the memory by the processor. The processor writes the information, which is stored in the memory, to all areas of the cache at predetermined timing. In addition, the processor performs access to all the areas of the cache at predetermined timing so as to cause a cache miss, by using memory address information corresponding to data stored in the cache. |
