Protecting memory by requiring all accessing programs to be modified

摘要

A method of operating control apparatus with a storage device programmable by way of a programming device comprises the step of performing the erasure and overwriting of the contents of the storage device each time with the execution of a data processing program section and with the use of data. The program section or the data is or are made available in such a manner that modification (S2) is required before use for the production of an erasure and/or an overwriting and that this modification is performed only when it is ascertained (S1) that an entry into the program section has taken place or will take place or can take place as intended. The invention may be used in a vehicle control system.
