    Abstract: A circuit produces a voltage for the erasure or programming of a memory cell. The circuit includes a capacitor, and a discharge circuit connected to a first terminal of the capacitor. The discharge circuit includes a first transistor, a drain of which is connected to the first terminal of the capacitor. The first transistor activates the discharge circuit when a discharge signal is received by a gate of the first transistor. The discharge circuit includes a slow discharge arm and a fast discharge arm parallel-connected to the source of the first transistor. The discharge circuit produces a low discharge current or a high discharge current for discharging the capacitor as a function of an operating mode selection signal.

    Abstract: The invention concerns an integrated circuit comprising a detection circuit (10) and a rectifier circuit (20) associated in series, to supply a rectified voltage (HV1, HV1), and a low voltage regulating circuit (30, 34) which receives the rectified voltage (HV1) and supplies a low voltage (Vcc). The invention is characterised in that the circuit further comprises a voltage producing circuit (100) which receives the rectified voltage (HV1) and produces high voltage (HT) different from the low voltage (Vcc). In one embodiment, the circuit also includes a memory (40) comprising a memory plane (42), the memory plane receiving the low voltage (Vcc) and the high voltage (HT).
