    摘要: A memory array with write feedback includes a number of row lines intersecting a number of column lines, a memory element connected between one of the row lines and one of the column lines, an electrical condition supply to be selectively applied to one of the row lines; and a feedback control loop to control an electrical condition supplied by the electrical condition supply. A method for setting the state of a memory element within a memory array includes applying an electrical condition to the memory element within the memory array, sensing a resistive state of the memory element, and controlling the electrical condition based on the sensed resistive state to cause the memory element to reach a target resistance.

    摘要: A shiftable memory is employed in a system and a method to shift a contiguous subset of stored data within the shiftable memory. The shiftable memory includes a memory having built-in shifting capability to shift a contiguous subset of data stored by the memory from a first location to a second location within the memory. The contiguous subset has a size that is smaller than a total size of the memory. The system further includes a processor to provide an address and the length of the contiguous subset. The method includes selecting the contiguous subset of data and shifting the selected contiguous subset.

    摘要: A stateful negative differential resistance device includes a first conductive electrode and a second conductive electrode. The device also includes a first material with a reversible, nonvolatile resistance that changes based on applied electrical energy and a second material comprising a differential resistance that is negative in a locally active region. The first material and second material are sandwiched between the first conductive electrode and second conductive electrode. A method for using a stateful NDR device includes applying programming energy to the stateful NDR device to set a state of the stateful NDR device to a predetermined state and removing electrical power from the stateful NDR device. Power-up energy is applied to the stateful NDR device such that the stateful NDR device returns to the predetermined state.
