NON-VOLATILE MEMORY DETERMINATION APPARATUS, CONTROL METHOD OF NON-VOLATILE MEMORY DETERMINATION APPARATUS AND ON-VEHICLE APPARATUS

摘要

PROBLEM TO BE SOLVED: To determine reliability of a non-volatile memory accurately.SOLUTION: An on-vehicle apparatus includes a non-volatile memory having a storage area for check, a ROM for storing check data to be written into the storage area for check, a data processing unit 103 for performing writing and deleting the check data to be stored in the ROM to the storage area for check of the non-volatile memory predetermined times, and a determination unit 104 for determining reliability of the non-volatile memory based on a state of the check data written into the storage area for check by the data processing unit 103.SELECTED DRAWING: Figure 3
