ABSTRACT:
A voltage regulator for electrically programmable non-volatile memory cells includes a gain stage which is supplied a voltage from a voltage booster connected to a supply voltage reference, having an input terminal connected to an output of a voltage divider and an output terminal connected to a pull-up transistor of a pull-up and pull-down differential pair to output the regulated voltage for programming at least one column or bit line of the memory cells. The voltage regulator also includes a second gain stage having an input terminal connected to a second output of the voltage divider. The second stage has an output connected to turn on the pull-down transistor in the complementary pair upon the regulated voltage exceeding a predetermined value.
