Abstract
The row decoder includes, for each word line of the memory, a respective biasing circuit receiving at the input a row selection signal switching, in preset operating conditions, between a supply voltage and a ground voltage and supplying at the output a biasing signal for the respective word line switching between a first operating voltage, in turn switching at least between the supply voltage and a programming voltage higher than the supply voltage, and a second operating voltage, in turn switching at least between the ground voltage and an erase voltage lower than the ground voltage. Each biasing circuit includes a level translator circuit receiving at the input the row selection signal and supplying as output a control signal switching between the first and the second operating voltages and an output driver circuit receiving as input the control signal and supplying at the output the biasing signal.
