Abstract

A description is given of a method for writing to and reading from non-volatile memories 20, comprising a plurality of memory cells 2 each of which stores one data element, in which the writing to each cell is carried out by changing the impedance of the cell from a first value, corresponding to a logical state (data) to a second value, corresponding to a second logical state, and the reading of each cell 2 is carried out by applying, to the input 6 of the cell, an interrogation signal which is propagated in the cell with a delay correlated with the set impedance value, and by discriminating between the stored data according to the delay of the output signal with respect to the interrogation signal. <IMAGE>
