Abstract: A method for management of the programming controls in a multilevel device is provided. During the control step cells are not controlled all together but they are conveniently selected in order to reduce the source resistance and consumption effect, but without penalizing change times.

Abstract: A voltage regulator with quick response includes: an output terminal supplying a regulated voltage; and at least a first boost circuit, controlled for alternately accumulating a first charge in a first operating condition and supplying the first charge to the output terminal in a second operating condition. In addition, the first boost circuit is provided with a compensation stage supplying the output terminal with a second charge substantially equal to the first charge, when the first boost circuit is in the first operating condition.

Abstract: A circuit design of a transistor connected as a diode, in particular to a design able to reduce the threshold voltage of the transistor and equal to the difference of the threshold voltage of the used transistors in the circuit disposal. The circuit design includes a first pMOS transistor having a second nMOS transistor connected as a diode connected between the gate and the drain of the first transistor and a current generator connected to the gates of the two transistors.
