Claim:
1. A device for generating a reference voltage, the device comprising: a first non-volatile memory cell comprising a control-gate transistor and a reading transistor; and a second equivalent memory cell; wherein the control-gate transistor comprises a gate terminal, a body, a first conduction terminal, and a second conduction terminal, the first conduction terminal and the second conduction terminal being connected together to form a control-gate terminal; and wherein the reading transistor comprises a gate terminal connected to the gate terminal of the control-gate transistor to form a floating-gate terminal, a body, a third conduction terminal and a fourth conduction terminal; wherein a source terminal of the first non-volatile memory cell and a source terminal of the second equivalent memory cell are connected together; and wherein the device is configured so that the reference voltage is acquired on the floating-gate terminal and is determined by conditions of supply of conduction terminals of the first non-volatile memory cell and the second equivalent memory cell.
