Abstract
A programming circuitry for a resistor of a resistive random-access memory (ReRAM) is provided. The programming circuitry includes a current-limiting circuit; a current-terminating circuit including a current measurement circuit and a control circuit; and a voltage-limiting circuit, wherein the current-limiting circuit, the current-terminating circuit, and the voltage-limiting circuit operate in concert. Any one of the current-limiting circuit, the current-terminating circuit, and the voltage-limiting circuit may comprises an operational amplifier or a current conveyor.
