    摘要: A non-volatile memory cell with a programmable unipolar switching element, and a method of programming the memory element are disclosed. In some embodiments, the memory cell comprises a programmable bipolar resistive sense memory element connected in series with a programmable unipolar resistive sense switching element. The memory element is programmed to a selected resistance state by application of a selected write current in a selected direction through the cell, wherein a first resistance level is programmed by passage of a write current in a first direction and wherein a second resistance level is programmed by passage of a write current in an opposing second direction. The switching element is programmed to a selected resistance level to facilitate access to the selected resistance state of the memory element.

    摘要: An anti-parallel diode structure and method of fabrication is presently disclosed. In some embodiments, an anti-parallel diode structure has a semiconductor region comprising a first insulator layer disposed between a first semiconductor layer and a second semiconductor layer. The semiconductor region can be bound on a first side by a first metal material and bound on a second side by a second metal material so that current below a predetermined value is prevented from passing through the semiconductor region and current above the predetermined value passes through the semiconductor region.
