Abstract

See full text

The present disclosure relates to a method wherein a state of an integrated circuit between a first state (e.g., CLOSED), allowing a reading access to the first area of fuse-type non-volatile memory by a processor, and a second state (e.g., OPEN), forbidding the reading access to the memory to the processor, is conditioned to a verification, by a finite state machine, of values of a first fuse word of the memory, representative of a number of transitions to the first state and of a second fuse word of the memory, representative of a number of transitions to the second state.
