Information processing system with longevity evaluation

摘要

An information processing system (1) includes a dynamic random access memory (14), a processor for information processing in cooperation with the dynamic access memory, and a built-in diagnosis module including a longevity evaluation device, the longevity evaluation device comprising, a timer (21) for measuring an elapsed time after data is entered into a memory device, a read controller (22) for reading the data from the memory device when the elapsed time reaches a predetermined time, and an evaluator (23) for evaluating a longevity of the memory device based on an existence of an error in the data read by the read controller and the elapsed time.
