1. A method for processing a non-volatile memory designed to store words containing data bits and control bits allowing error correction with an error correction code, the method comprising: storing information in a memory plane including writing in the memory plane at least one modified digital word modified with respect to at least one initial digital word not having any erroneous bit, said at least one modified digital word containing a bit having a modified value with respect to the value of a corresponding bit in the at least one initial digital word, other bits of the at least one modified digital word having values identical to corresponding bits in the initial digital word, the position of the modified bit in said at least one modified digital word defining a value of digital information.
