Patent abstract
A phase change memory device with memory cells (2) formed by a phase change memory element (3) and a selection switch (4). A reference cell (2a) formed by an own phase change memory element (3) and an own selection switch (4) is associated to a group (7) of memory cells to be read. An electrical quantity of the group of memory cells is compared with an analogous electrical quantity of the reference cell, thereby compensating any drift in the properties of the memory cells.
