    Abstract: High density NVRAM. The invention is a an array of memory cells capable of storing at least a megabit of information, each memory cell including a memory plug that includes a memory element that switches from a first resistance state to a second resistance state upon application of a first write voltage of a first polarity and reversibly switches from the second resistance state to the first resistance state upon application of a second write voltage of polarity opposite to the first polarity.

    Abstract: Providing a cross point memory array with memory plugs exhibiting a characteristic hysteresis. The memory plugs exhibit a hysteresis that, in the low resistive state, the first write threshold voltage is the point above which any voltages applied across the memory plug have substantially no effect on the resistive state and below which a voltage pulse will alter the resistance of the memory plug. Similarly, in the high resistive state, the second write threshold voltage is the point below which any voltages applied across the memory plug have substantially no effect on the resistive state and above which a voltage pulse will alter the resistance of the memory plug. The read voltages applied to the memory plug are typically above the first write threshold voltage and lower than the second write threshold voltage.

    Abstract: A re-writable memory that uses resistive memory cell elements with non-linear IV characteristics is disclosed. Non-linearity is important in certain memory arrays to prevent unselected cells from being disturbed and to reduce the required current. Non-linearity refers to the ability of the element to block the majority of current up to a certain level, but then, once that level is reached, the element allows the majority of the current over and above that level to flow.

    Abstract: A 2-terminal trapped charge memory device is disclosed with voltage switchable multi-level resistance. The trapped charge memory device has a trapped charge memory body sandwiched between two electrodes. The trapped charge memory body can be made of a variety of semiconducting or insulating materials of single-crystalline, poly-crystalline or amorphous structure while containing current carrier traps whose respective energy levels and degrees of carrier occupancy, modifiable by the height and width of an applied write voltage pulse, determine the resistance. The mechanism of modification can be through carrier tunneling, free carrier capturing, trap-hopping conduction or Frenkel-Poole conduction. The current carrier traps can be created with dopant varieties or an initialization procedure.

    Abstract: Providing a reference voltage to a cross point memory array. The invention is a cross point memory array and some peripheral circuitry that, when activated, provides a reference voltage to a cross point array in order to prevent unselected conductive array lines from floating to an undesired voltage. The peripheral circuitry can be activated before, after or during selection of a specific memory plug. If the peripheral circuitry is activated during selection, only the unselected conductive array lines should be brought to the reference voltage. Otherwise, all the conductive array lines can be brought to the reference voltage.

    Abstract: Providing a multi-output multiplexor. The invention is multi-output multiplexor that, depending on the control signals, allows various modulating circuits to pass no voltage, pass some voltage or pass all the voltage on one of the mulitplexor's ports., A modulating circuit can be fully turned on, partially turned on, or fully turned off.
