Title: Electronic memory and electronic device provided with such a memory

Abstract: The electronic memory (2) includes blocks (M1 to MN) associated respectively with protective sequences (P1 to PN) and decision units (D1 to DN) which control access to the memory blocks. The protective sequences include at least two bits. In order to protect the memory blocks against physical actions which could vary the inscribed code, access to a block is closed when the corresponding protective sequence has identical logical states.
