Memory diagnostic method, device, and non-transitory computer-readable storage medium for diagnosing a memory used by a process during execution of the process
In a memory diagnostic method, a fixed domain stores data that are not changed during process execution. A variable domain stores data that are subject to writing during process execution. A fixed domain diagnostic part adds an error-detecting code to data to be stored in the fixed domain. The fixed domain diagnostic part compares an error-detecting code calculated from data read from the fixed domain with the added error-detecting code to determine whether there is any data error. A variable domain diagnostic part temporarily stores data stored in the variable domain in a memory region different from the memory storing the data, and writes known data in the variable domain where the temporarily stored data were stored. The variable domain diagnostic part reads data from the region where the known data were written and determines whether the data is the same as the written known data.
