Abstract
A circuit device programs non-volatile memory cells having a single voltage supply, wherein each cell comprises a floating gate transistor having source and drain terminals and a control gate terminal, with the drain terminal being supplied a program voltage from a voltage booster circuit. The device includes a means of supplying a constant drain current to the drain terminal of the memory cell; an element for sampling the drain current drawn through the cell; and a means of voltage feedback driving the control gate terminal of the cell according to the sampled value of the drain current.
