Memory unit backup using checksum
A memory system backup for use in a tightly or loosely coupled multiprocessor system. A plurality of primary memory units (13, 14, 15) having substantially the same configuration are backed up by a single memory unit (20) of similiar configuration.

| Zusammenfassung: | A memory system backup for use in a tightly or loosely coupled multiprocessor system. A plurality of primary memory units (13, 14, 15) having substantially the same configuration are backed up by a single memory unit (20) of similiar configuration. The backup memory unit holds the checksum of all data held in all primary memory units. In the event of the failure of one of the primary memory units its contents can be recreated based on the data in the remaining non-failed memory unit and the checksum in the backup unit. |
