  • Patent number: 7981773
    Abstract: Systems and methodologies are provided for forming a diode component integral with a memory cell to facilitate programming arrays of memory cells created therefrom. Such a diode component can be part of a PN junction of memory cell having a passive and active layer with asymmetric semiconducting properties. Such an arrangement reduces a number of transistor-type voltage controls and associated power consumption, while enabling individual memory cell programming as part of a passive array. Moreover, the system provides for an efficient placement of memory cells on a wafer surface, and increases an amount of die space available for circuit design.

  • Patent number: 7378682
    Abstract: The present memory device has first and second electrodes, a passive layer between the first and second electrodes and on and in contact with the first electrode, and an active layer between the first and second electrodes and on and in contact with the passive layer and second electrode, for receiving a charged specie from the passive layer. The active layer is a mixture of (i) a first polymer, and (ii) a second polymer for enhancing ion transport, improving the interface and promoting a rapid and substantially uniform distribution of the charged specie in the active layer, i.e., preventing a localized injection of the charged species. These features result in a memory element with improved stability, a more controllable ON-state resistance, improved switching speed and a lower programming voltage.

  • Patent number: 7379317
    Abstract: A memory array includes first and second sets of conductors and a plurality of memory-diodes, each connecting in a forward direction a conductor of the first set with a conductor of the second set. An electrical potential is applied across a selected memory-diode, from higher to lower potential in the forward direction, intended to program the selected memory-diode. During this intended programming, each other memory-diode in the array has provided thereacross in the forward direction thereof an electrical potential lower than its threshold voltage. The threshold voltage of each memory-diode can be established by applying an electrical potential across that memory-diode from higher to lower potential in the reverse direction. By so establishing a sufficient threshold voltage, and by selecting appropriate electrical potentials applied to conductors of the array, problems related to current leakage and disturb are avoided.

  • Patent number: 7199394
    Abstract: Systems and methodologies are provided for of enabling a polymer memory cell to exhibit variable retention times for stored data therein. Such setting of retention time can depend upon a programming mode and/or type of material employed in the polymer memory cell. Short retention times can be obtained by programming the polymer memory cell via a low current or a low electrical field. Similarly, long retention times can be obtained by employing a high current or electrical field to program the polymer memory cell.

  • Patent number: 7122853
    Abstract: Systems and methodologies are provided for simplifying a polymer memory cell's operation by employing a post polymer growth treatment to form ionic or super ionic metal compounds therein. Such post polymer growth treatment facilitates distribution and mobility of metal ions (or charged metallic molecules) within an active layer of the polymer memory cell, and mitigates (or eliminates) a need for initialization procedures. Moreover, the post treatment of the present invention can also facilitate controlling a distribution of various thresholds (e.g., write and erase threshold), and set them to predetermined values Accordingly, variability in threshold values of polymer memory cells that can result from initialization processes can be mitigated (or eliminated), and thicker polymer layers can be employed without an initialization penalty.
