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: The present invention relates to the internal gettering of impurities in semiconductors by metal alloy clusters. In particular, intermetallic clusters are formed within silicon, such clusters containing two or more transition metal species. Such clusters have melting temperatures below that of the host material and are shown to be particularly effective in gettering impurities within the silicon and collecting them into isolated, less harmful locations. Novel compositions for some of the metal alloy clusters are also described.

摘要: Shiftable memory employs ring registers to shift a contiguous subset of data words stored in the ring registers within the shiftable memory. A shiftable memory includes a memory having built-in word-level shifting capability. The memory includes a plurality of ring registers to store data words. A contiguous subset of data words is shiftable between sets of the ring registers of the plurality from a first location to a second location within the memory. The contiguous subset of data words has a size that is smaller than a total size of the memory. The memory shifts only data words stored inside the contiguous subset when the contiguous subset is shifted.

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.
