    摘要： Structures and methods of converting Multi-Level Cell (MLC) Non-Volatile Memory (NVM) into multi-bit information are disclosed. In MLC NVM system, multi-bit information stored in NVM cell is represented by the states of NVM cell threshold voltage levels. In this disclosure, “P” states of NVM cell threshold voltage levels are divided into “N” groups of threshold voltage levels. Each group contains “M” states of multiple threshold voltage levels of NVM cells, where P=N×M. The “M” states of NVM cell threshold voltage levels in each group are sensed and resolved by applying one correspondent gate voltage to the group. By applying “N” multiple gate voltages, the whole “P” states of NVM cell threshold voltage levels can be sensed and efficiently converted into storing bits in the MLC NVM cells.

    摘要： 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. Using the distinctive threshold voltage associated with the different stored charges, the output voltage from the drain is distinctively recognized and converted back to the original n-bit word. A similar method for a PFET EEPROM is also disclosed.

    摘要： A Non-Volatile Memory (NVM) cell in an NVM array is read out using other NVM cells in the array as a load element. Conventional load elements such as MOS transistors or resistors used to vary the bitline potential for the NVM cell readout in conventional NVM arrays are replaced with NVM cell(s) in the array. The omission of the extra MOS transistors or resistors for the load elements not only saves silicon area but also simplifies the bitline sensing circuitry design in the NVM array.

    摘要： A method and system are provided for forecasting keyword search volume. Keywords are categorized by concept and by the amount of data available for use in predicting future behavior. The keywords and/or the categories can also be categorized as seasonal or non-seasonal. A category level seasonal variation pattern can then be calculated based on keywords in the category that have sufficient historical data. A search volume can then be predicted for one or more keywords, with an appropriate calculation algorithm being selected based on the concept category, seasonal classification, and historical data available for the keywords.

    摘要： 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.

    摘要： Techniques for cross-selling keywords among keyword bidding entities (e.g., advertisers) based upon bidding patterns are provided. Utilizing a keyword suggestion tool in accordance with one embodiment, upon receipt of a first keyword, may examine all additional keywords that have been paired with the first keyword in the bidding patterns of other bidding entities and recommend one or more of the paired keywords to the bidding entity for consideration. In another embodiment, a keyword suggestion tool, upon receipt of a keyword from a first bidding entity, may examine the bidding pattern of the first bidding entity in comparison to the bidding patterns of other bidding entities to identify bidding entities that are similar to the bidding entity. Recommendations may then be made to the first bidding entity based upon keywords that the identified similar bidding entities have bid.
