Abstract
An integrated circuit comprises a memory zone, a test mode and at least one binary type of lock, said lock when it is in a first state permitting the operation of the integrated circuit in the test mode and when it is in a second state prohibiting the operation of the integrated circuit in test mode, wherein the integrated circuit comprises a dysfunction circuit that works when the lock is in the first state, said dysfunction circuit preventing the memory from working normally. The use of a dysfunction circuit makes it possible to reveal components whose test locks have not been activated as being defective.
