ABSTRACT:
A device for selecting an operating mode of an integrated circuit, including a non-volatile memory programmable after manufacturing exhibiting prior to any programming an initial content, means for storing a first signature representative of the initial content of the memory, means for calculating a second signature representative of a current content of the memory, and means for evaluating a difference between the first and second signatures and for deactivating an operating mode selection signal when the difference is greater than a predetermined threshold.
