    摘要: A microprocessor including a memory and a central processing unit configured to sign a binary word written in the memory, and during the reading of a binary word in the memory, verify the signature of the binary word and, if the signature is invalid, launching a protective action of the memory. According to the invention, the central processing unit is configured to execute a write instruction of a binary word accompanied by an invalid signature in a memory zone, so that a later read of the memory zone by the central processing unit launches the protective action.
