Abstract
A semiconductor memory includes a plurality of memory cells connected to one another to form a matrix of memory cells. A charge pump is connected to the matrix of memory cells. A plurality of controllable connection elements are provided, with each controllable connection element connected between an output terminal of the charge pump and a respective column line. Connected to the output of the charge pump is the series connection of a first element equivalent to a controllable connection element, and a second element equivalent to a memory cell in a predetermined biasing condition. A voltage regulator is connected between the second equivalent element and the input terminal of the charge pump for regulating the output voltage therefrom based upon a voltage present between terminals of the second equivalent element.
