REGULATEUR DE HAUTE TENSION INTERNE VPP POUR CIRCUITS INTEGRES

A circuit for regulating the internal programming voltage (Vpp) supplied to an integrated circuit memory device. The invention limits the internal programming voltage to a maximum value no greater than the field assisted breakdown voltage of on-chip transistors and/or the field transistor threshold voltage. Representatives of the several different types of transistors provided on an integrated circuit substrate are incorporated into the voltage regulating circuit. The regulator transistors are placed in the circuit in such a way that they are designed to break down first in the event of an excessive internal programming voltage (Vpp). In this way, the regulator transistors limit the voltage sent to the operating circuitry of the integrated circuit.
