Abstract
A generator circuit generates a reference voltage on an output terminal connected to a matrix of non-volatile memory cells and includes a comparator positioned between a common node and the output terminal. The comparator has first and second input terminals and an output terminal suitable for supplying a compared voltage given by comparing first and second voltage values present on the first and second input terminals. The circuit includes a reference cell inserted between the common node and a first voltage reference. Advantageously, the reference cell comprises a floating gate with a contact terminal coupled to a biasing block, having an input terminal connected to the output terminal of the generator circuit and being suitable for periodically biasing the floating gate contact terminal at a biasing voltage of a second voltage reference.
