Abstract

A memory comprises memory cells arranged in a memory array, and an address decoder to apply memory cells selection signals to the memory array according to a read address applied to the memory. The memory comprises an address reconstruction circuit which reconstructs at least one part of the read address from the memory cells selection signals, and supplies a first reconstructed address able to detect an error injection affecting the selection signals. Particularly but not exclusively applicable to the integrated circuits for chip cards.
