    • The memory comprises a matrix of cells (10), a charge pump (11), a voltage regulator, controllable connection elements (12) each connected between the output of the charge pump (11) and a column line of the matrix of cells, and means (14) for selectively activating the connection elements.
      To arrange for the voltage of a cell in a predetermined biasing condition, for example, the programming condition, to be independent of temperature variations and of manufacturing and design parameters, the memory comprises a first element (12') equivalent to a connection element (12) and a second element (10') equivalent to a memory cell (10) in the predetermined biasing condition. These equivalent elements are connected in series with one another between the output terminal and the common terminal of the charge pump (11). The regulator (15, 17) is connected between the second equivalent element (10') and the input of the charge pump (11) in order to regulate the output voltage of the charge pump (11) in dependence on the voltage across the second equivalent element (10').
