PROBLEM TO BE SOLVED: To provide an information processor which can prevent any operational abnormality caused by a physical abnormality of a semiconductor storage means without changing any hardware configuration, and improve the reliability. SOLUTION: In a microcomputer as an information processor, a storage RAM area 5a to save the data to be continuously used even after the resetting is provided in a RAM area 5, a CPU 1 performs the memory check to the RAM area 5 including the storage RAM area 5a, and uses the data present in the storage RAM area 5a in the normal processing operation only when the result of the memory check is excellent. An empty area 7a which is a migration area for migrating the data in the storage RAM area 5a during the memory check is provided in a general register area 7. COPYRIGHT: (C)2003,JPO
