Abstract
The disclosed invention presents a self-tracking reference circuit that compensates for IR drops and achieves the target resistance state at different temperatures after write operations. The disclosed self-tracking reference circuit includes a replica access path, a configurable resistor network, a replica selector mini-array and a step current generator that track PVT variations to provide a PVT tracking level for RRAM verify operation.
