    摘要： A large bit size core memory which maximizes usable flux includes at least one array of low drive toroidal magnetic memory cores, a sense-inhibit conductor pair passing through the array in a given direction to inductively couple all cores in the array, a plurality of perpendicular drive conductors, each passing through the array perpendicular to the sense-inhibit conductor pair and inductively coupling a portion of the cores in the array, a plurality of parallel drive conductors, each passing through the array parallel to the sense-inhibit conductor pair and inductively coupling a portion of the cores in the array, and driving and switching circuitry coupled to drive selected a core during a read portion of a memory cycle with a current which rapidly increases to approximately provide the coercive force MMF to the core and then increases relatively slowly toward the full drive current. The resulting core output switching pulse received by a strobed sense amplifier has an early noise component from delta noise and coupling noise and a subsequent logic 1 switching pulse which is extremely stable with respect to normal variations in temperature and drive current, which has a flat, low magnitude peak that satisfies sense amplifier requirements and which is sufficiently delayed to permit attenuation of the noise signals.

    摘要： Read/write structures for three-dimensional memories are disclosed. In one embodiment, a three-dimensional memory includes a plurality of data storage layers fabricated in parallel on top of one another to form a three-dimensional structure. Each data storage layer is able to store bits of data in the form of magnetic domains. The memory further includes a column of write elements that is operable to write a column of magnetic domains to the first data storage layer representing a column of bits. The first data storage layer is patterned into a plurality of magnetic conductors aligned transverse to the column of write elements. A control system may inject spin-polarized current pulses in the magnetic conductors to transfer the column of magnetic domains laterally within the first data storage layer. The control system may transfer of the column of magnetic domains perpendicularly from the first data storage layer to another data storage layer.

    摘要： Disclosed herein is a semiconductor memory device for reducing a current consumption used for operating a write command or a read command. The semiconductor memory device includes a global data latch unit for latching a global data loaded on a global data line in response to a first write enable signal to thereby generate a global latch data; a local data write driving unit for receiving the global latch data to output a local data to a local data line in response to a second write enable signal; and a write driver control unit for generating the first write enable signal and the second write enable signal to inactivate the first write enable signal when a write operation is not performed.

    摘要： A novel nonvolatile memory element or cell comprising a memory means consisting of at least one superconducting ring (21, 22) and a detector means consisting of a MOSFET. The superconducting ring and the MOSFET are arranged in such a manner that a magnetic flux created by the superconducting ring (21, 22) passes through a channel zone of the MOSFET. Information is held in the superconducting ring in a form of permanent current and is detected electrically as variation in the conductivity of the channel zone of the MOSFET.
