Abstract
Described herein is a method for storing a datum in a first and a second memory cells of a nonvolatile memory. The storage method envisages programming the first and second memory cells in a differential way, by setting a first threshold voltage in the first memory cell and a second threshold voltage different from the first threshold voltage in the second memory cell, the difference between the threshold voltages of the two memory cells representing a datum stored in the memory cells themselves.
