タの自動修正装置。[Claims for Utility Model Registration] (1) An electrically rewritable storage means storing main data, at least one electrically rewritable storage means storing backup data, and both storage means. A read/write control means for controlling reading and writing of data;
data correctness determining means for temporarily storing data read out via the write control means and determining whether the data is correct; a signal processing means for stopping the system when the data is correct; and when the data correctness determining means determines that the data is abnormal, the read/write control means is designated with an address for reading the backup data so that the data becomes normal. and address designation means for designating an address for rewriting the normal data with abnormal data. (2) When there is a plurality of storage means storing the backup data, each of the storage means is configured as an independent one-chip, and the storage data according to claim (1) of the above-mentioned utility model registration claim is characterized in that: Automatic correction device.
