ABSTRACT:
A voltage regulator for programming non-volatile memory cells, which comprises an amplifier stage being powered between a first and a second voltage reference and having a first input terminal connected to a resistive divider of the first reference voltage and an output terminal fed back to said input through a current mirror, and a source-follower transistor controlled by the output and connected to the cells through a programming line. Also provided is a MOS transistor which connects to ground the programming line and a corresponding resistive path connected between the current mirror and the second voltage reference.
