  • Patent number: 8781754
    Abstract: Disclosed are a method of and system for detecting a consensus motif in a data sequence. The method comprises the steps of obtaining the data sequence, identifying potential signal (PS) segments of interest in the data sequence, and carrying out comparison and alignment processes amongst the PS segments to extract the consensus motif. Preferably, an unsupervised motif discovery process is used to identify the PS segments. More specifically, this may be done by extracting all common motifs across the sequence using the unsupervised motif discovery process; and for each of at least selected positions in the sequence, computing the weighted sum of the common motifs that cover said position. The PS segments that cover the positions where said number is above a given threshold may then be identified as the PS segments.

    Abstract: A method of obtaining a more accurate estimate of a signal correction parameter(s) in sequencing-by-synthesis operations, such as incomplete extension rates, carry forward rates, and/or signal droop rates. The sequencing operation produces signal data. A model is constructed to simulate a population of template strands as it undergoes the sequencing process and becomes divided into different phase-states as the sequencing-by-synthesis progresses. For example, the model may be a phase-state model. The output from the model is used to adjust the signal correction parameter(s). For example, the model may be fitted to the signal data. This fitting results in a more accurate estimate of the signal correction parameter(s). In another embodiment, the signal droop rate is modeled as a decaying function and this decaying function is fitted to the signal data to obtain an improved estimate of the signal droop rate.

Also, a difference between a statistical size value for one chromosome can be compared to a statistical size value of another chromosome to identify a significant shift in size. A genotype and haplotype of the fetus may also be determined using a size distribution to determine whether a sequence imbalance occurs in a maternal sample relative to a genotypes or haplotype of the mother, thereby providing a genotype or haplotype of the fetus.

  • Patent number: 8576602
    Abstract: Polysilicon diodes fabricated in standard CMOS logic processes can be used as program selectors for One-Time Programmable (OTP) devices, using electrical fuse, contact/via fuse, contact/via anti-fuse, or gate-oxide breakdown anti-fuse etc. as OTP element The diode can be constructed by P+/N+ implants on a polysilicon as a program selector. The OTP device has an OTP element coupled to a polysilicon diode. The OTP devices can be used to construct a two-dimensional OTP memory with the N-terminals of the diodes in a row connected as a wordline and the OTP elements in a column connected as a bitline. By applying a high voltage between a selected bitline and a selected wordline to turn on a diode in a selected cell for suitable duration of time, a current flows through an OTP element may change the resistance state. The cell data in the OTP memory can also be read by turning on a selected wordline and to couple a selected bitline to a sense amplifier.

  • Publication number: 20130286709
    Abstract: An anti-fuse one-time-programmable (OTP) nonvolatile memory cell has a P well substrate with two P? doped regions. Another N+ doped region, functioning as a bit line, is positioned adjacent and between the two P? doped regions on the substrate. An anti-fuse is defined over the N+ doped region. Two insulator regions are deposited over the two P? doped regions. An impurity doped polysilicon layer is defined over the two insulator regions and the anti-fuse. A polycide layer is defined over the impurity doped polysilicon layer. The polycide layer and the polysilicon layer function as a word line. A programmed region, i.e., a link, functioning as a diode, is formed on the anti-fuse after the anti-fuse OTP nonvolatile memory cell is programmed. The array structure of anti-fuse OTP nonvolatile memory cells and methods for programming, reading, and fabricating such a cell are also disclosed.
