Abstract: A driver circuit for operating a memory cell, adapted to be coupled to at least one memory cell through a respective output node, said driver circuit including: a first circuit for supplying the memory cell with a first read reference voltage through the output node; a second circuit for supplying the memory cell with a second read reference voltage through the output node; and a third circuit for controlling an operation of the second circuit, wherein a range of the second read reference voltage at the output node is wider than a range of the first read reference voltage at the output node during a read operation on the memory cell.

Abstract: A selective non-volatile memory programming method for a selected memory cell in a memory array is described so as to reduce or avoid program disturbance on an unselected memory cell. This selective programming method comprises: applying a programming pulse to a selected memory cell to be programmed and an unselected memory cell, wherein the programming pulse allows a change of the unselected memory cell within a range specified; boosting a region of the unselected memory cell; and setting a threshold time of the programming pulse, wherein the threshold time is defined when an absolute magnitude of a voltage difference between a floating gate of the unselected memory cell and the boosted region of the unselected memory cell reaches a threshold value defined.
