Abstract
A CMOS twin-tub negative voltage switching architecture is for a non-volatile memory device and includes a negative voltage multiplier for generating a increased voltage value starting from a single main power supply. A voltage regulator feedback is connected to the voltage multiplier for regulating the generated negative voltage value; and a plurality of independent switch circuits each one receiving as an input the negative voltage value and producing as an output a predetermined local negative voltage.
