Abstract
An information processing system includes a dynamic random access memory, 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 for measuring an elapsed time after data is entered into a memory device, a read controller for reading the data from the memory device when the elapsed time reaches a predetermined time, and an evaluator 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.
Claims20
An information processing system comprising:
- a dynamic random access memory;
- 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 including:
- a timer for measuring an elapsed time after data is entered into a memory device;
- a read controller for reading the data from the memory device when the elapsed time reaches a predetermined time;
- and
- an evaluator 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.
A longevity evaluation method performed by using an information processing system, the information processing system including a dynamic random access memory, a processor for information processing in cooperation with the dynamic access memory, and a built-in diagnosis module including a longevity evaluation device, the method including:
- measuring an elapsed time after data is entered into a memory device;
- reading the data from the memory device when an elapsed time reaches a predetermined time;
- and
- evaluating a longevity of the memory device based on an existence of an error in the data and the elapsed time.
A longevity evaluation program performed by an information processing system, the information processing system including a dynamic random access memory, a processor for information processing in cooperation with the dynamic access memory, and a built-in diagnosis module including a longevity evaluation device, the program comprising:
- measuring an elapsed time after data is entered into a memory device;
- reading the data from the memory device when the elapsed time reaches a predetermined time;
- and
- evaluating a longevity of the memory device based on an existence of an error in the data and the elapsed time.
