Abstract
A method of programming a plurality of memory cells are connected in parallel between first and second supply references and having their gate terminals connected together and, through row decoding means, also connected to an output terminal of an operational amplifier that is adapted to generate a word voltage signal, the first voltage reference being provided by a charge pump circuit. The programming method uses a program loop that includes the cells to be programmed and the operational amplifier, the charge pump circuit thus outputting a voltage ramp whose slope is a function of the cell demand. A programming circuit adapted to implement the method is also provided.
