    Abstract: A two-terminal memory array includes a plurality of first and second conductive traces. An address unit operatively applies a select voltage across a selected pair of the first and second conductive traces and applies a non-select voltage potential to unselected traces. A total current flowing in the selected first conductive trace and a leakage current flowing through unselected second conductive traces are sensed by a sense unit in a one cycle or a two cycle pre-read operation. The total and leakage currents can be combined with a reference signal to derive a data signal indicative of one of a plurality of conductivity profiles that represent stored data. The conductivity profiles can be stored in a resistive state memory element that is electrically in series with the selected first and second conductive traces.

    Abstract: A movable terminal in a two terminal memory array. A storage medium is disposed between two terminals, one of the terminals being movable relative to the second terminal. Either one of the terminals or both terminals might actually move, resulting in one terminal being moved relative to the other terminal. A memory element disposed between the two terminals has a conductance that is responsive to a write voltage across the electrodes.

    Abstract: Cross point memory array using distinct voltages. The invention is a cross point memory array that applies a first select voltage on one conductive array line, a second select voltage on a second conductive array line, the two conductive array lines being uniquely defined. Additionally, an unselect voltage is applied to the unselected conductive array lines. The unselect voltage can be applied before, after or during the selection process. The unselect voltage can be approximately equal to the average of the first select voltage and the second select voltage.

    Abstract: A conductive memory stack is provided. The memory stack includes a bottom electrode, a top electrode and a multi-resistive state element that is sandwiched between the electrodes. The bottom electrode can be described as having a top face with a first surface area, the top electrode has a bottom face with a second surface area and the multi-resistive state element has a bottom face with a third surface area and a top face with a fourth surface area. The multi-resistive state element's bottom face is in contact with the bottom electrode's top face and the multi-resistive state element's top face is in contact with the top electrode's bottom face. Furthermore, the fourth surface area is not equal to the second surface area.

    Abstract: A memory array with enhanced functionality is presented. Each cell in the array includes a pair of memory element electrodes. A read current across the pair of memory element electrodes is indicative of stored information and different write voltage levels across the pair of memory element electrodes are employed to store nonvolatile information. The array has at least one enhanced functionality portion that performs operations selected from the group consisting of reference, error correction, device specific storage, defect mapping tables, and redundancy.
