Title: Circuit for reading non-volatile memories

Abstract: A circuit for reading a non-volatile memory cell has an output terminal for providing an output current, and a control terminal for receiving a voltage for controlling the output current. The reading circuit includes a feedback circuit which can be connected electrically to the output terminal and to the control terminal to generate the control voltage from a reference signal and from the output current. The feedback circuit also includes a current-amplification circuit having a first terminal for receiving a current-error signal derived from the reference signal and from the output current, and a second terminal for supplying an amplified current.
