    摘要: A matchline sense circuit for detecting a rising voltage on a matchline of a CAM array is disclosed. The circuit initially precharges a matchline to ground before turning on a current source to supply current to the matchline and raise the voltage of the matchline. A reference matchline sense circuit generates a self-timed control signal to keep the current supply turned on for a predetermined duration of time. Sensed data on the matchlines are latched after the current source is turned off and the matchlines are precharged to ground. Because the matchline sense circuit of the present invention precharges the matchlines to ground instead of the supply voltage, VDD, less power is consumed. By sensing the rise of the matchline voltage to an n-channel transistor threshold potential, the matchline sensing operation speed is increased.

    摘要: A composition is provided comprising a negatively charged group, an oligonucleotide sequence and at least none or one nuclease-resistant linkage group to form a chemically-enhanced primer. The chemically-enhanced primer can be used for sequencing and fragment analysis. Methods for synthesizing the primer as well as a method of preparing DNA for sequencing and a method of sequencing DNA and kits containing the chemically-enhanced primer are also provided. The method of sequencing DNA can comprise contacting amplification reaction products with the composition under conditions in which excess amplification primer is degraded by the nuclease and the chemically-enhanced primer is essentially non-degraded.

    摘要: Modified porous materials are disclosed having interconnected, complexly shaped three-dimensional surfaces. The modification is accomplished by crosslinking the three-dimensional surfaces and/or by coating the three-dimensional surfaces with a layer of a predetermined material. The porous materials are macro structures including at least one of nano-features, micro-features, and combinations thereof. The modifying accomplishes changing surface properties of the porous materials, changing the three-dimensional surfaces, and/or rendering the porous materials substantially stable in a predetermined environment.
