Abstract
A power management unit for a non-volatile memory device is proposed. The power management unit includes means for providing a reference voltage, resistive means for deriving a reference current from the reference voltage, means for generating a plurality of operative voltages from a power supply voltage, and means for regulating the operative voltages; in the power management unit of the invention, for each operative voltage the means for regulating includes means for deriving a scaled reference current from the reference current according to a scaling factor, further resistive means for deriving a rating voltage from the scaled reference current, means for deriving a measuring voltage from the operative voltage and the rating voltage, and means for controlling the operative voltage according to a comparison between the measuring voltage and the reference voltage.
