  • Publication number: 20210233958
    Abstract: Various embodiments of the present application are directed towards a bipolar selector having independently tunable threshold voltages, as well as a memory cell comprising the bipolar selector and a memory array comprising the memory cell. In some embodiments, the bipolar selector comprises a first unipolar selector and a second unipolar selector. The first and second unipolar selectors are electrically coupled in parallel with opposite orientations and may, for example, be diodes or some other suitable unipolar selectors. By placing the first and second unipolar selectors in parallel with opposite orientations, the first unipolar selector independently defines a first threshold voltage of the bipolar selector and the second unipolar selector independently defines a second threshold voltage of the bipolar selector. As a result, the first and second threshold voltages can be independently tuned by adjusting parameters of the first and second unipolar selectors.
