Data securing and restoring in data processor

摘要

The method involves securing and restoring data in a data processor (10) through storing the data in at least two non-volatile memories (20, 24) which are arranged in physically separate assembly groups (16, 14). At each activation of the data processing arrangement, the data of the first memory (24) are first of all examined for consistency, in which case they are copied into the second memory (20). In case of inconsistency of the data in the first memory, the data of the second memory are examined for consistency, and are copied in case of consistency into the first memory. A memory arranged on a rear wall (14) of the data processing arrangement is preferably used as the first memory.
