  • Patent number: 7286388
    Abstract: In the present method of programming a memory device from an erased state, the memory device includes first and second electrodes, a passive layer between the first and second electrodes, and an active layer between the first and second electrodes. In the programming method, (i) an electrical potential is applied across the first and second electrodes from higher to lower potential in one direction to reduce the resistance of the memory device, and (ii) an electrical potential is applied across the first and second electrodes from higher to lower potential in the other direction to further reduce the resistance of the memory device.

  • Patent number: 7176113
    Abstract: The present invention pertains to implementing a lightly doped channel (LDC) implant in fashioning a memory device to improve Vt roll-off, among other things. The lightly doped channel helps to preserve channel integrity such that a threshold voltage (Vt) can be maintained at a relatively stable level and thereby mitigate Vt roll-off. The LDC also facilitates a reduction in buried bitline width and thus allows the bitlines to be brought closer together. As a result more devices can be formed or “packed” within the same or a smaller area.

  • Publication number: 20060256608
    Abstract: Provided herein is method of programming a resistive memory device, the resistive memory device including a first electrode, a second electrode, a passive layer between the first and second electrode, and an active layer between the first and second electrodes. In the programming method, an electrical potential is applied across the first and second electrodes from higher to lower potential in the direction from the active layer to the passive layer so that electronic charge carriers enter the active layer and are held by traps therein. In erasing the memory device, an electrical potential is applied across the first and second electrodes from higher to lower potential in the direction from the passive layer to the active layer so that electronic charge carriers are moved from the active layer.
