Abstract
A phase-change memory cell to be read is associated with a phase-change reference memory cell placed in a SET state. The reference memory cell has a structure that is identical to that of the memory cell. A first voltage is applied to the memory cell to cause output of a first current. A second voltage is applied to the reference memory cell to cause output of a second current. A sense amplifier is coupled to the memory cell and to the reference memory cell and is configured to compare respective values of the first current and of the second current and generate output information representative of the logic value of the datum stored by the memory cell.
