Other AbstractThis invention claims a method and device based on hardware redundant the safety of instrument high reliability memory and method for diagnosing. This invention can be connected to mcu two memory is respectively the data memory and backup memory: Data memory is used for programme and data backup operation of the memory is used for data storage device data backup; Mcu the data in memory diagnosis of area is divided into n small diagnostic region the backup memory in the backup area is divided into n small backup region of each small diagnosis area corresponds to a backup region small; Mcu order to each small diagnostic region respectively to diagnose: Mcu at a certain of the diagnostic region to diagnose it controls the corresponding program running in corresponding size of the backup region after finishing diagnosis in the small backup region of the data copy back corresponding to the size of the diagnostic region. The invention uses hardware and software a method of combining and it improves the meter memory diagnosis of real time property and reduces the memory diagnosis difficulty of design.
