A method for addressing redundant columns in a nonvolatile memory, which receives, at inputs, selection addresses and comprises a plurality of redundant columns, each including a respective bit line and a plurality of memory cells connected to the bit line. The addressing method comprises the steps of: detecting a transition in the selection addresses; starting charging of all the bit lines upon detection of the transition in the addresses; then detecting whether one of the redundant columns is addressed; should one of the redundant columns be found to be addressed, proceeding with charging of the bit line of the redundant column addressed and interrupting charging of the bit lines of the redundant columns not addressed; and should none of the redundant columns be found to be addressed, interrupting charging of all the bit lines.
