Abstract: A method and a circuit are for regulating the source terminal voltage of a non-volatile memory cell during the cell programming and/or reading phases. The method includes a phase of locally regulating the voltage value and includes comparing the source current of the cell array with a reference current. A fraction of the source current is converted to a voltage and compared with a voltage generated from a memory cell acting as a reference and being programmed to the distribution with the highest current levels. The comparison may be used for controlling a current generator to inject, into the source terminal, the current necessary to keep the predetermined voltage thereof at a constant value.

Abstract: A method and program-load circuit is for regulating the voltages at the drain and body terminals of a non-volatile memory cell being programmed. These voltages are applied from a program-load circuit connected in a conduction pattern to transfer a predetermined voltage value to at least one terminal of the memory cell. The method includes a step of regulating the voltage value locally, within the program-load circuit, to overcome the effect of a parasitic resistor present in the conduction pattern.

Abstract: A voltage regulator having a comparator with an output terminal that is the output of the regulator, terminals for connection to a voltage supply, a source of a reference voltage connected to an input terminal of the comparator, and a feedback circuit connected between the output terminal and the other input terminal of the comparator. To prevent transients upon the transition from the standby state to the active state, there is provided a second reference-voltage source that provides a reference voltage substantially equal to that of the first source, a switch for connecting the second source to the other input terminal of the comparator, and a control circuit that can activate the supply of the regulator and can close the switch for a predetermined period of time when the supply of the regulator is activated.
