Abstract
An integrated circuit is provided that allows for the use of the same supply voltage pin to receive both a normal operating voltage for the integrated circuit (IC) and a one-time-programmable (OTP) memory program voltage sufficient to program an OTP memory located on the integrated circuit. In one embodiment, when an OTP programming voltage is received at a supply voltage pin of the IC, the OTP programming voltage is provided to the OTP memory of the integrated circuit and the OTP programming voltage is regulated to the normal operating voltage level prior to providing the voltage to the internal circuitry of the integrated circuit. As such, the present invention establishes a dual-purpose supply voltage pin, thereby eliminating the need for a separate OTP programming voltage pin on the integrated circuit.
