    摘要: The present invention provides methods and apparatus for adjusting voltages of bit and word lines to program a two terminal memory cell. The invention may include setting a first line connected to a memory cell to a first voltage from a first line standby voltage, charging a second line connected to the memory cell to a predetermined voltage from a second line standby voltage, and switching the first line from the first voltage to a second voltage. The voltage difference between the first voltage and the predetermined voltage is such that a safe voltage results that does not program the memory cell. A voltage difference between the second voltage and the predetermined voltage is such that a programming voltage operative to program the memory cell results.

    摘要: A non-volatile memory core comprises one or more memory bays. Each memory bay comprises one or more memory blocks that include a grouping of non-volatile storage elements. In one embodiment, memory blocks in a particular memory bay share a group of read/write circuits. During a memory operation, memory blocks are transitioned into active and inactive states. The process of transitioning blocks from an inactive state to an active state includes enabling charge sharing between a memory block entering the active state and another memory block that was previously in the active state. This charge sharing improves performance and/or reduces energy consumption for the memory system.

    摘要: A method of biasing a nonvolatile memory array. The nonvolatile memory array includes a first and second plurality of Y lines, a plurality of X lines, a first and second plurality of two terminal memory cells. Each first and second memory cell is coupled to one of the first or second plurality of Y lines and one of the plurality of X lines, respectively. Substantially all of the first plurality and second plurality of Y lines are driven to a Y line unselect voltage. At least one selected Y line of the first plurality of Y lines is driven to a Y line select voltage while floating remaining Y lines of the first plurality of Y lines and while driving substantially all of the second plurality of Y lines to the Y line unselect voltage.

    摘要: A memory array includes a sensing circuit for sensing bit line current while keeping the voltage of the selected bit line substantially unchanged. The word lines and bit lines are biased so that essentially no bias voltage is impressed across half-selected memory cells, which substantially eliminates leakage current through half-selected memory cells. The bit line current which is sensed arises largely from only the current through the selected memory cell. A noise detection line in the memory array reduces the effect of coupling from unselected word lines to the selected bit line. In a preferred embodiment, a three-dimensional memory array having a plurality of rail-stacks forming bit lines on more than one layer, includes at least one noise detection line associated with each layer of bit lines. A sensing circuit is connected to a selected bit line and to its associated noise detection line.

    摘要: A multiple polarity reversible charge pump circuit is disclosed which, in certain embodiments, may be configured to generate a positive voltage at times and may be reversed to generate a negative voltage at other times. Such a charge pump circuit is advantageous if both the positive and negative voltage are not simultaneously required. In certain other embodiments, a charge pump circuit generates a high output current for only a positive boosted voltage in one mode of operation, but lower current positive and negative boosted voltage outputs in another mode of operation. Use with certain erasable memory array technologies is disclosed, particularly certain resistive passive element memory cells, and more particularly in a three-dimensional memory array.

    摘要: A structure and a method of manufacturing a three dimensional memory using a number of bit line masks that is less than the number of device layers. A first bit line mask is used to form a first bit line layer in a first device level. The first bit line layer comprises first bit lines. The first bit line mask is also used to form a second bit line layer in a second device level. The second bit line layer comprises second bit lines. The first bit lines and the second bit lines have different electrical connections to a bit line connection level despite employing the same mask pattern.

    摘要: A non-volatile storage system includes a substrate, control circuitry on the substrate, a three dimensional memory array (above the substrate) that includes a plurality of memory cells with reversible resistance-switching elements, and circuits to SET and RESET the resistance-switching elements. The circuits that RESET the resistance-switching elements provide a pulse to the memory cells that is large enough in magnitude to SET and RESET the memory cells, and long enough to potentially RESET the memory cell but not long enough to SET the memory cells.
