摘要： A method for voltage detection and lockout. The method of one embodiment first compares a reference voltage to a supply voltage to determine whether the voltage supply voltage is greater than the reference voltage. The reference voltage is validated by determining whether the reference voltage is at least a valid voltage potential. An unlock signal is generated if the supply voltage is greater than the reference voltage and if the reference voltage is valid.

摘要： A method and apparatus to segment a programmable non-volatile memory array into at least two banks. The banks include memory cells. Each bank in the at least two banks is provided with a local programming voltage. Each local programming voltage is independent of the other local programming voltages supplied to the other banks.

摘要： A method for generating a positive temperature correlated clock frequency is described. The method comprises conducting current through a resistor to charge a capacitor. When the capacitor is charged to a trip point of the inverter at the input of the inverter chain, a transition in an output signal of an inverter chain is triggered. The capacitor is discharged through a grounding device when the output signal activates said grounding device.
