  • Patent number: 7385867
    Abstract: A method of operating a memory device adapted for determining a program/erase state of a memory cell in the memory device. The method includes applying a drain operation voltage to a drain of the memory cell so that the memory cell generates a working voltage. The working voltage is a function of the drain operation voltage. Then, the working voltage to the drain operation voltage is differentiated to obtain a slope of the working voltage to the drain operation voltage. The program/erase state of the memory cell is determined according to the slope.

  • Patent number: 7184336
    Abstract: A method for evaluating threshold voltage distribution of memory cells. The method comprises connecting all sources and drains of memory cells in a memory array to a fixed voltage; measuring charge pumping current characteristic of a single memory cell versus a first gate voltage and second gate voltage respectively. The total charge pumping current characteristic of a memory array is then measured versus a first gate voltage and second gate voltage respectively. The charge pumping current characteristics of the single memory cell is compared to that of the memory array to obtain a range of threshold voltage distribution.

  • Patent number: 7033758
    Abstract: Methods are provided for highly sensitive and rapid in situ detection of a nucleic acid analyte of a known sequence. The method employs oligonucleotide probes in a series of optimized steps to amplify a signal and decrease background. Sensitivity is enhanced such that the method can detect as few as 1–2 copies of nucleic acid analyte per sample, the sample containing a cell, tissue or similar biological material. Methods of detecting and identifying the position of the nucleic acid analyte in a cell are also provided.

  • Publication number: 20060074856
    Abstract: Methods for patent summarization. A digital file comprising an issued patent document or a published application is acquired. At least one claim string is acquired from the digital file. Multiple elements are acquired from the claim string. A part-of relationship architecture among a portion of the elements is generated according to the claim string. At least one as-is relationship for at least one of the elements is generated according to the claim string. At least one association relationship for at least one of the elements is generated according to the claim string. The part-of relationship architecture, as-is relationship and association relationship are displayed.

  • Publication number: 20060020708
    Abstract: A system for peer-to-peer (p2p) communication. A instant message is received from a first daemon corresponding to a first instant messaging application type originating with a first client, and transmits the instant message to a second daemon corresponding to a second instant messaging application type originating with a second client. A third daemon receives the instant message using communication protocol corresponding to the first instant messaging application type. A message switching unit acquires the second instant messaging application type corresponding to the third daemon identity, and acquires a second daemon identity. A fourth daemon transmits the instant message to the second daemon corresponding to the second daemon identity using communication protocol corresponding to the second instant messaging application type.

  • Publication number: 20020150716
    Abstract: In data-storage media such as rewritable optical discs (DVD−RAM, DVD+RW, DVD−RW, DVR, CD−RW and PD), the current need for the disc to be initialised before it can be used is eliminated. This is achieved by depositing on the disc, immediately before and/or after the record layer itself has been deposited, a layer of additional material that induces the record layer to become deposited in its crystalline state, or to be transformed spontaneously into that state. One specific material, which has this effect on record layers of GeSbTe and/or AgInSbTe, is Sb2Te3.

  • Patent number: 5615334
    Abstract: A memory reflection scheme is disclosed including a snarfing agent provided with efficient memory reflection circuitry for snarfing data. The memory reflection circuitry is for snarfing particular data written back from a write back agent to a memory subsystem agent. In response to unsuccessfully snarfing the particular data written back from the write back agent to the memory subsystem agent, the memory reflection circuitry issues a command to read the particular data from the memory subsystem agent. However, the memory reflection circuitry only issues such a command if the write back agent successfully writes back the particular data to the memory subsystem agent.
