  • Patent number: 8422301
    Abstract: A nonvolatile semiconductor memory device in accordance with an embodiment includes a memory cell array. A control unit performs control of repeating a write operation, a write verify operation, and a step-up operation, the write operation being an operation to apply a write pulse voltage to a selected memory cell and an intermediate voltage to an unselected memory cell. The control unit controls the step-up operation such that, in a first period, the intermediate voltage is maintained at a constant value, and, in a second period, the intermediate voltage is raised by a certain value. The control unit controls the step-up operation such that the first period includes an operation to raise the write pulse voltage by a first step-up value, and the second period includes an operation to raise the write pulse voltage by a second step-up value smaller than the first step-up value.

  • Publication number: 20130058170
    Abstract: A nonvolatile semiconductor storage device according to an embodiment includes a drive circuit. A voltage applied to a dummy wire connected to a first dummy cell adjacent to a memory string is defined as a first dummy wire voltage, a voltage applied to a selection wire connected to a first memory cell adjacent to the first dummy cell is defined as a first selection wire voltage, and a voltage applied to a selection wire connected to a second memory cell adjacent to the first memory cell is defined as a second selection wire voltage. When the second selection wire voltage is lower than the first dummy wire voltage in an erase operation, the drive circuit controls voltages so that a difference between the first dummy wire voltage and the second selection wire voltage is less than a difference between the first dummy wire voltage and the first selection wire voltage.

  • Patent number: 8350309
    Abstract: A select gate transistor has a select gate electrode composed of a first-level conductive layer and a second-level conductive layer. The first-level conductive layer has contact areas. The second-level conductive layer has its portions removed that are located above the contact areas. Two adjacent select gate electrodes that are adjacent to each other in the column direction are arranged such that the contact areas of one select gate electrode are not opposed to the contact areas of the other select gate electrode. One select gate electrode has its first- and second-level conductive layers removed in their portions that are opposed to the contact areas of the other select gate electrode.

  • Patent number: 8316063
    Abstract: Provided is a technique for a data-driven database which frees a user from having to be conscious of a sequence in which instructions of a program for accessing a database are described, an interrelation of data items, and the like, and from having to describe redundant instructions. A data-driven database processor includes: schema definition storage means 2 for storing a schema definition of a database 24; derived definition storage means 3 for storing a derived definition describing a cause-and-effect relationship that exists when a value of a given data item is derived from a value of another data item; derived definition processing means 26 for generating a trigger program 27 that makes a chain of changes to values of data items based on the cause-and-effect relationship described in the derived definition; and a database management system 23 for executing the trigger program 27 when a change is made to the other data item that affects the value of the given data item.

  • Patent number: 8167335
    Abstract: The present invention discloses a fender liner attached to a motor vehicle wheel house. The fender liner includes a breathable base material layer produced by forming a fiber assembly into a shape along the wheel house and a protective layer made of waterproof material. The protective layer is superimposed on a surface of the base material layer that is opposite to a side facing the wheel house. The protective layer is provided with a plurality of through-holes that allow air to flow through the protective layer to the surface of the base material layer on which the protective layer is superimposed.
