  • Publication number: 20190057748
    Abstract: In an embodiment, a method is provided for controlling a level of a read current in a non-volatile memory that is powered by a supply voltage includes. A model current representative of an actual current able to flow during a readout through a read path of the memory is determined based on the value of the supply voltage. The model current is compared to a reference current having a reference value. A control signal is generated. The control signal is to control the generation of the read current having a level equal to the lowest value between a fraction of the value of the model current and the reference value.
