  • Publication number: 20100254194
    Abstract: The invention provides a method for reading a first data storage of a memory cell. The method comprises sensing a first current of the memory cell by applying a first bit line voltage on the memory cell. When the first current is larger than a first reference current with respect to the first bit line voltage, the first data storage is determined to be at an un-programmed state. Otherwise, a second current of the memory cell is sensed by applying a second bit line voltage on the memory cell. When the difference between the first current and the second current is larger than the difference between the first reference current and the second reference current, the first data storage is determined to be at the un-programmed state.

  • Publication number: 20100214841
    Abstract: A memory apparatus and a method thereof for operating a memory are provided herein. The apparatus has the memory and a controller. The memory has a plurality of memory cells, and each the memory cells has a first side and the second side. Each of the first side and the second side is programmable to store one bit of data. The controller programs the first sides and the second sides of the memory cells to different levels. Several threshold voltage distributions of the programmed memory cells could be overlapped with each other. The controller distinguishes the bits of the memory cells by comparing the threshold voltages of the memory cells with the different levels and by comparing the threshold voltages with those of neighbor sides.

  • Patent number: 7775816
    Abstract: An electronic device case structure includes a case body, a pivoting seat, a pushing member, and a driving member. An accommodating slot is formed on the case body for a peripheral device to be inserted therein. The case body has a disposition hole communicating with the accommodating slot and an internal space of the case body. The pivoting seat is disposed in the case body, and the pushing member is pivoted to the pivoting seat. The pushing member has a pushing segment, protruding in the accommodating slot through the disposition hole and a connecting segment. The driving member includes a coupling end connected to the connecting segment and an operation end, The operation end is to be pressed to make the driving member move inwards, so as to have the pushing segment to move towards the outside of the accommodating slot, thereby pushing and ejecting the peripheral device.

  • Publication number: 20100193763
    Abstract: A layer of nanoparticles having a dimension on the order of 10 nm is employed to form a current constricting layer or as a hardmask for forming a current constricting layer from an underlying insulator layer. The nanoparticles are preferably self-aligning and/or self-planarizing on the underlying surface. The current constricting layer may be formed within a bottom conductive plate, within a phase change material layer, within a top conductive plate, or within a tapered liner between a tapered via sidewall and a via plug contains either a phase change material or a top conductive material. The current density of the local structure around the current constricting layer is higher than the surrounding area, thus allowing local temperature to rise higher than surrounding material. The total current required to program the phase change memory device, and consequently the size of a programming transistor, is reduced due to the current constricting layer.

  • Publication number: 20100151652
    Abstract: A multi-level, phase change memory cell has first and second thermal isolation materials having different thermal conductivity properties situated in heat-conducting relation to first and second boundaries of the phase change material. Accordingly, when an electrical current is applied to raise the temperature of the memory material, heat is drawn away from the memory material asymmetrically along a line orthogonal to electric field lines between the electrodes.

    Abstract: A phase change memory cell includes first and second electrodes electrically coupled by a phase change element. At least a section of the phase change element comprises a higher reset transition temperature portion and a lower reset transition temperature portion. The lower reset transition temperature portion comprises a phase change region which can be transitioned, by the passage of electrical current therethrough, from generally crystalline to generally amorphous states at a lower temperature than the higher reset transition temperature portion. The phase change element may comprise an outer, generally tubular, higher reset transition temperature portion surrounding an inner, lower reset transition temperature portion.

  • Publication number: 20100097851
    Abstract: A method of programming a phase change device includes selecting a desired threshold voltage (Vth) and applying a programming pulse to a phase change material in the phase change device. The applying of the programming pulse includes applying a quantity of energy to the phase change material to drive at least a portion of this material above a melting energy level. A portion of the energy applied to the phase change material is allowed to dissipate below the melting energy level. The shape of the energy dissipation from the phase change material is controlled until the energy applied to the phase change material is less than a quenched energy level, to cause the phase change device to have the desired Vth. A remaining portion of the energy applied to the phase change material is allowed to dissipate to an environmental level.
