  • Patent number: 9870823
    Abstract: A memory array includes wordlines, local bitlines, two-terminal memory elements, global bitlines, and local-to-global bitline pass gates and gain stages. The memory elements are formed between the wordlines and local bitlines. Each local bitline is selectively coupled to an associated global bitline, by way of an associated local-to-global bitline pass gate. During a read operation when a memory element of a local bitline is selected to be read, a local-to-global gain stage is configured to amplify a signal on or passing through the local bitline to an amplified signal on or along an associated global bitline. The amplified signal, which in one embodiment is dependent on the resistive state of the selected memory element, is used to rapidly determine the memory state stored by the selected memory element. The global bit line and/or the selected local bit line can be biased to compensate for the Process Voltage Temperature (PVT) variation.

  • Patent number: 9872275
    Abstract: A cellular communication system and method for delivering information, e.g., data and/or control-signaling, to a user equipment (UE) from a neighboring node are disclosed. The cellular communication system includes a first node configured to transmit information in one or more Multicast Broadcast Single Frequency Network (MBSFN) subframes over a radio frequency (RF) (ink between the first node and the UE, while the UE is being served by a second node. The first node can use a network-defined, dedicated portion of the MBSFN subframe for this purpose. Instead of only allowing the second node to send data/signaling messages to the UE, the disclosed techniques allow neighboring nodes to also deliver information to the UE. In particular, the neighboring nodes can transmit data and/or control-signaling to the UE using MBSFN subframes in order to minimize signaling overhead and signaling delay.

  • Patent number: 9869908
    Abstract: A system and device for driving high resolution monitors while reducing artifacts thereon. Utilization of Z-inversion polarity driving techniques to drive pixels in a display reduces power consumption of the display but tends to generate visible horizontal line artifacts caused by capacitances present between the pixels and data lines of the display. By introducing a physical shield between the pixel and data line elements, capacitance therebetween can be reduced, thus eliminating the cause of the horizontal line artifacts. The shield may be a common voltage line (Vcom) of the display.
