Abstract: A non-volatile memory device including an array of memory cells coupled to word lines and a row decoder, which includes a first and a second pull-down stage, which are arranged on opposite sides of the array, and include, respectively, for each word line, a corresponding first pull-down switching circuit and a corresponding second pull-down switching circuit, which are coupled to a first point and a second point, respectively, of the first word line. The row decoder moreover comprises a pull-up stage, which includes, for each word line, a corresponding pull-up switching circuit, which can be electronically controlled in order to: couple the first point to a supply node in the step of deselection of the word line; and decouple the first point from the supply node in the step of selection of the word line.
