Abstract
An information processing device according to an embodiment includes a memory and a mediation unit. The memory includes memory use areas that are allocated to respective tasks, and an identification-information area that identifies the tasks. The mediation unit mediates writing and reading, by one of the tasks, into and from one of the memory use areas. When accepting a request of the writing and reading from the one task, the mediation unit writes one of the identification informations corresponding to the one task into the identification-information area, further reads information memorized in the identification-information area at a predetermined timing, and detects an abnormality in the memory on the basis of the read information.
