  • Patent number: 8270193
    Abstract: Embodiments relate generally to semiconductors and memory technology, and more particularly, to systems, integrated circuits, and methods to implement a memory architecture that includes local bit lines for accessing subsets of memory elements, such as memory elements based on third dimensional memory technology. In at least some embodiments, an integrated circuit includes a cross-point memory array formed above a logic layer. The cross-point memory array includes X-lines and Y-lines, of which at least one Y-line includes groups of Y-line portions. Each of the Y-line portions can be arranged in parallel with other Y-line portions within a group of the Y-line portions. Also included are memory elements disposed between a subset of the X-lines and the group of the Y-line portions. In some embodiments, a decoder is configured to select a Y-line portion from the group of Y-line portions to access a subset of the memory elements.

  • Publication number: 20110188284
    Abstract: Embodiments of the invention relate generally to semiconductors and memory technology, and more particularly, to systems, integrated circuits, and methods to implement circuits configured to compensate for parameter variations in layers of memory by adjusting access signals during memory operations. In some embodiments, memory cells are based on third dimensional memory technology. In at least some embodiments, an integrated circuit includes multiple layers of memory, a layer including sub-layers of semiconductor material. The integrated circuit also includes an access signal generator configured to generate an access signal to facilitate an access operation, and a characteristic adjuster configured to adjust the access signal for each layer in the multiple layers of memory.

  • Publication number: 20110188283
    Abstract: Embodiments of the invention relate generally to semiconductors and memory technology, and more particularly, to systems, integrated circuits, and methods to implement circuits configured to compensate for parameter variations that affect the operation of memory elements, such as memory elements based on third dimensional memory technology. In at least some embodiments, an integrated circuit includes a cross-point array comprising memory elements disposed among word lines and bit lines, where a parameter can affect the operating characteristics of a memory element. The integrated circuit further includes a data signal adjuster configured to modify the operating characteristic to compensate for a deviation from a target value for the operating characteristic based on the parameter. In some embodiments, the memory element, such as a resistive memory element, is configured to generate a data signal having a magnitude substantially at the target value independent of variation in the parameter.

  • Publication number: 20060042045
    Abstract: The handle of wheelbarrow is commonly produced separately before they are welded together to form the entire handle. The process involves more steps and equipment, which has increased the producing cost relatively. The present invention provides a simpler process to fabricate the handle, where the narrow portion at the end portion part of the handle is integrally formed with the body portion of the handle for a wheelbarrow.

  • Publication number: 20060033311
    Abstract: The present invention is an improved wheelbarrow with a releasable container connected to a releasable locking system for easy pouring and requiring small leverage to lift the container. The improved wheelbarrow comprising a lever mounted directly on the handle part of the wheelbarrow support frame for easily release the container during removing load process. The lever is joined to a pivotal hook which is mounted on the body of the support frame by a cable. The container includes a fixture on the lower part rear end of the container. This is to secure the container to the releasable locking system when in loading or moving position. With the grasping of the lever, a tension force is formed and thus pulled the pivotal hook backward away from the hooked position. This releases the container from its secured position and can be easily lifted for emptying purposes.
