ABSTRACT:
A redundancy management method, particularly for non-volatile memories, includes the steps of: enabling, as a consequence of the presence of a pulsed read address transition signal of a memory line, and throughout the duration of the pulsed signal, the memory matrix line reading path, and blocking the selection of redundancy lines of the memory; and at the end of the pulsed signal, as a consequence of the absence/presence of a redundancy line read signal, confirming/disabling the selection of the lines of the memory matrix and blocking/releasing the selection of the redundancy lines. A redundancy management architecture for a memory matrix, adapted to perform the above method, blocks or releases redundancy line selection during address switching, but does not block selection of memory matrix word lines.
