  • Patent number: 7660154
    Abstract: Non-Volatile Memory (NVM) cells are connected in inverter configurations. The NVM inverter's Voltage Transfer Characteristics (VTC) is used to verify and adjust threshold voltage levels of a Multi-Level Cell (MLC) in an NVM. In one embodiment, the NVM cell is fast programmed to a specific threshold voltage level. The cell threshold level is then verified by applying a gate voltage corresponding to the selected threshold voltage to the NVM inverter. The output voltage of the NVM inverter in response to the applied level gate voltage is detected. When the output voltage of the NVM inverter is out of a predefined output voltage window for the selected threshold voltage level, a fine-tuning programming sequence is applied to the NVM cell until the threshold voltage of the NVM cell is inside the correspondent threshold voltage window. This verification and adjustment scheme for a MLC NVM allows the threshold voltage of the multi-level NVM cells for any specific level to be controlled to a desired accuracy.

  • Patent number: 7660786
    Abstract: A measurable means to evaluate a given relevancy verification process to a human decision process is provided. For example, a cognitive concept relationship (CCR) system can be utilized to provide a relevancy verification evaluation that is independent of the relevancy quality of the test data employed to train the relevancy verification algorithm under test. This provides a means to evaluate relevancy verification of, for example, keyword/item pairs for any number of business applications with different relevance standards and/or changes in relevance standards over time, without the need to manually re-label the test data and/or re-measure the algorithmic relevancy.

  • Patent number: 7650431
    Abstract: A method and system for providing location-based advertisements to requesting devices is provided. An advertisement system aggregates advertisements by collecting advertisements from multiple advertisement sources, extracting data from the collected advertisements, and storing the extracted data in a common format. After aggregating the advertisements, the advertisement system transforms each advertisement into multiple advertisement formats that are specific to protocols supported by the various device types. When the advertisement system receives queries for advertisements, it identifies matching advertisements and ranks them based on a location. The advertisement system then selects an advertisement format that is appropriate for the requesting device.

  • Patent number: 7627559
    Abstract: Usage context obtained from search query logs is leveraged to facilitate in discovery and/or similarity determination of key search phrases. A key phrase extraction process extracts key phrases from raw search query logs and breaks individual queries into a vector of the key phrases. A Similarity Graph generation process then generates a Similarity Graph from the output of the key phrase extraction process. Information relating to the similarity levels between two key phrases can be employed to restrict a search space for tasks such as, for example, online keyword auctions and the like. Thus, instances can be employed to find frequent misspellings of a given keyword, keyword/acronym pairs, key phrases with similar intention, and/or keywords which are semantically related and the like.

  • Patent number: 7606069
    Abstract: Storage of information represented by a multi-bit word in a single non-volatile memory cell is made possible by programming the threshold voltage of the non-volatile memory to a specific threshold level corresponding to the multi-bit word. Stored or generated multi-bit words are scanned and converted into a gate voltage to be applied to the non-volatile memory cell until the electrical response from the non-volatile memory cell indicates that the voltage generated from the specific multi-bit word which has been applied to the gate matches the information stored in the non-volatile memory cell. The matched multi-bit word is read out of storage and represents the stored bits in the single non-volatile memory cell.

  • Patent number: 7593391
    Abstract: The Hi-SD CBS includes a termination unit and pluralities of distributed customer premise units connected through the cable TV (CATV) network. The radio signals in Hi-SD CBS are propagating inside the co-axial cable. To insure the linking quality between the termination unit and customer premise devices, preamble procedures are required to adjust the transmitting radio power, the receiver sensitivity, the channel equalization, and to synchronize the transceivers for data transmission between the termination unit and the customer premise devices. To guarantee a secure link between the termination unit and an individual customer premise device or a group of premise devices, the termination unit provides different encryption keys to different customer premise device groups.

  • Publication number: 20090175079
    Abstract: Innovative structures and methods to store information capable of being represented by an n-bit binary word in electrically erasable Programmable Read-Only memories (EEPROM) are disclosed. To program a state below the highest threshold voltage for an N-type Field Effect Transistor (NFET) based EEPROM, the stored charge in the floating gate for the highest threshold voltage is erased down to the desired threshold voltage level of the EEPROM by applying an appropriate voltage to the control gate and drain of the NFET. The erase-down uses drain-avalanche-hot hole injection (DAHHI) for the NFET memory device to achieve the precise threshold voltage desired for the NFET EEPROM device. The method takes advantage of the self-convergent mechanism from the DAHHI current in the device, when the device reaches a steady state. For a “READ” operation, a read voltage is applied to the control gate and the drain is connected by a current load to the positive voltage supply.

    Abstract: Methods and systems for displaying data retrieved from a multi-dimensional data source via an interactive data diagram. A graphical user interface is responsive to input from a user to retrieve multi-dimensional data for display via an interactive data diagram. The interactive data diagram displays multi-dimensional data in a hierarchical structure that includes a plurality of dimension levels and one or more member levels within each dimension level. A user specifies a change to the display structure by selecting a displayed member level in the hierarchical structure. The interactive data diagram is responsive to the user specified change to generate a drilled down data diagram displaying detailed dimension and member levels related to the selected member level.

  • Publication number: 20090021984
    Abstract: A metal oxide semiconductor field effect transistor (MOSFET) in a non-volatile memory cell has a source, a drain and a channel region between the source and the drain, all formed in a substrate of opposite conductivity type to the conductivity type of the source and drain. The MOSFET is programmed by connecting the drain electrode to the supply source of the main voltage, Vcc, provided to said non-volatile memory cell and supplying selected voltages to the source and substrate so as to invert a portion of the channel region extending from the source toward the drain. The inverted portion of the channel region ends at a pinch-off point before reaching the drain. By controlling the reverse bias across the PN junction between the source and the substrate, the pinch-off point of the inversion region is pulled back toward the source thereby to increase the programming efficiency of the MOSFET.

  • Patent number: 7457873
    Abstract: In accordance with a method and system for centralized network usage tracking, documents on a network server include a reference to content on a centralized logging server. When one of the documents is accessed by a client computer, the process of rendering the content at the client computer includes requesting the content from the logging server. The logging server, upon receipt of such a request, logs information embedded in the request and returns a trivial response which requires little time and which rendering of need not be perceivable by the user.
