Abstract
A time-based sensing circuit to convert resistance of a programmable resistive element into logic states is disclosed. A programmable resistive memory has a plurality of programmable resistive devices. At least one of the programmable resistive devices can have at least one programmable resistive element (PRE) that is selectively accessible via a wordline and a bitline. The bitline can be coupled a capacitor and the capacitor can be precharged and discharged. By comparing the discharge rate of the capacitor to discharge rate of a reference capacitor in a reference unit (e.g., reference cell, reference resistance, reference selector, etc.), the PRE resistance can be determined larger or smaller than a reference resistance and then converting the PRE resistance into a logic state.
