Abstract

Magnetic random-access memory (MRAM) circuits are provided herein. In one example implementation, an MRAM circuit includes control circuitry coupled to a magnetic tunnel junction (MTJ) element in series with a selector element. This control circuitry is configured to adjust current through the selector element when the selector element is in a conductive state. The circuit also includes a compensation circuitry configured to compensate for a offset voltage across the selector element in the conductive state based on adjustments to the current through the selector element. An output circuit is also configured to report a magnetization state of the MTJ element.
