  • Patent number: 8380693
    Abstract: Systems, methods, and computer readable storage mediums are provided to automatically identifying a classified website. A website is determined to be a candidate site based on a set of heuristics. From among pages constituting the candidate site one or more pages are determined to be listing page candidates and one or more pages are determined to be detail page candidates. Then a listing page score is determined using a listing page classifier. Similarly, a detail page score is determined using a detail page classifier. The listing page and detail page scores each indicate the likelihood that the pages are part of a classified website. A candidate site score is determined based in part on a combination of the listing page score and the detail page scores. Then when the candidate site score is above a threshold the candidate site is determined to be a classified website.

  • Patent number: 7919367
    Abstract: A non-volatile memory cell with increased charge retention is fabricated on the same substrate as logic devices using a single-gate conventional logic process. A silicide-blocking dielectric structure is formed over a floating gate of the NVM cell, thereby preventing silicide formation over the floating gate, while allowing silicide formation over the logic devices. Silicide spiking and bridging are prevented in the NVM cell, as silicide-blocking dielectric structure prevents silicide metal from coming in contact with the floating gate or adjacent sidewall spacers. The silicide-blocking dielectric layer may expose portions of the active regions of the NVM cell, away from the floating gate and adjacent sidewall spacers, thereby enabling silicide formation on these portions. Alternately, the silicide-blocking dielectric layer may cover the active regions of the NVM cell during silicide formation. In this case, silicide-blocking dielectric layer may be thinned or removed after silicide formation.

  • Patent number: 7633810
    Abstract: A non-volatile memory system including an array of cells, each having an access transistor and a capacitor sharing a floating gate. The access transistors in each row are fabricated in separate well regions, which are independently biased. Within each row, the source of each access transistor is coupled to a corresponding virtual ground line, and each capacitor structure is coupled to a corresponding word line. Alternately, the source of each access transistor in a column is coupled to a corresponding virtual ground line. Within each column, the drain of each access transistor is coupled to a corresponding bit line. Select memory cells in each row are programmed by band-to-band tunneling. Bit line biasing prevents programming of non-selected cells of the row. Programming is prevented in non-selected rows by controlling the well region voltages of these rows. Sector erase operations are implemented by Fowler-Nordheim tunneling.

  • Publication number: 20090162334
    Abstract: An ex vivo method for generating a population of Treg capable of suppressing rejection of an organ or tissue transplant from a donor animal, comprises culturing CD4+ T cells from a recipient animal in the presence of IFN-? plus either donor specific or third-party antigen presenting cells, and harvesting a population of Treg capable of suppressing rejection in the recipient animal. The Treg can be administered, for example intravenously to the recipient, preferably immediately prior to the transplant to suppress transplant rejection. A similar strategy applicable to generating a population of Treg capable of suppressing an autoimmune condition in an animal wherein the animal mounts an immune reaction against an autoantigen, comprises culturing CD4+ T cells from the animal in the presence of cells presenting the autoantigen and IFN-? and harvesting a population of autoantigen reactive Treg.
