  • Publication number: 20060244975
    Abstract: A Fabry-Perot (FP) interferometer includes substantially parallel first and second reflecting surfaces spaced apart by an optical gap between the first and second reflecting surfaces. The FP interferometer also has a mechanism for controlling the optical gap. The mechanism includes a plurality of electrostatic control plates. Each electrostatic control plate has a fixed control-plate area. Each control plate is adapted to control the optical gap by application of a control-plate voltage. The control-plate areas are related by integral ratios.

  • Patent number: 6873543
    Abstract: Embodiments of the present invention provide a memory device. In one embodiment, the memory device comprises an array of memory cells configured to provide resistive states, a read circuit configured to sense the resistive states and a resistor. The resistor is configured to provide a resistance to the read circuit that is configured to select the resistor and sense the resistance to test the read circuit.

  • Publication number: 20050052893
    Abstract: A resistive cross point memory cell array comprising a plurality of word lines, a plurality of bit lines, a plurality of cross points formed by the word lines and the bit lines, and a plurality of memory cells, each of the memory cells being located at a different one of the cross points, wherein a first bit line comprises a distributed series diode along an entire length of the bit line such that each of the associated memory cells located along the first bit line is coupled between the distributed series diode and an associated word line.

  • Patent number: 6839263
    Abstract: A memory array according to a particular embodiment of the invention includes a substrate, a plurality of first select-lines disposed in a plurality of planes generally parallel to the substrate, a plurality of second select-lines formed in pillars disposed generally orthogonal to the substrate, a plurality of memory cells coupled to the first select-lines and the second select-lines, and a current path connection providing a continuous current path through a selected plurality of the pillars to heat the selected pillars and cause at least one memory cell associated with the selected pillars to be reset.

  • Patent number: 6826077
    Abstract: Systems and methods for storing data are provided. A representative system for storing data includes a magnetic random access memory (MRAM) device having a plurality of memory cells. Each memory cell includes a magnetic tunnel junction and a non-magnetic tunnel junction that are connected in series. The magnetic tunnel junction stores a bit value corresponding to a logic high (1) or a logic low (0). The non-magnetic tunnel junction provides little resistance when the memory cell is being read, and a substantially high resistance when the memory cell is not being read. As a result, a negligible level of parasitic current leaks through memory cells that are not being read.
