Abstract
A non-volatile memory device includes a memory array, a reading circuit, a column decoder stage, and a read supply voltage generator. The column decoder stage includes selectable bitlines and selection switches. A read supply voltage generator includes a voltage regulation circuit and a dummy column decoder coupled to an output of the voltage regulation circuit and having electrical characteristics correlated to the selected read path. The voltage regulation circuit is configured to receive a first electrical quantity correlated to a desired voltage value on the selected bitline and a second electrical quantity correlated to a desired current value for the selected bitline and to generate a regulated read supply voltage for the column decoder stage.
