Abstract: This invention pertains to the discovery that the human NELL-1 gene induces or upregulates bone mineralization. The NELL-1 gene or gene product thus provides a convenient target for screening for modulators of bone mineralization. In addition, NELL-1 can be used to facilitate repair of bone fractures and/or to generally increase bone density.

Abstract: A method for a deep power down mode is described for a memory chip in which voltage regulators and charge pumps are turned off, memory cell voltages are floated, and support circuit internal power supply voltages are replaced by voltages that are derived from the external chip voltage. Prior to being placed into a deep power down mode, all memory cells are placed into a precharge state from which the memory cell voltages are floated upon entering the deep power down mode. Pass through circuits connect externally derived voltages to the support circuit power supply voltage lines, controlled by a deep power down signal. Maintaining a voltage bias on the support circuits prevents latch up problems when the memory chip is brought out of the deep power down mode.

Abstract: A method and apparatus are provided for improving the efficiency in charge pump systems for low power applications. This first embodiment provides a method and apparatus which defines a charge pump output voltage high target which turns off a charge pump enable signal and a charge pump outlet voltage low target which turns on a charge pump enable signal. A second embodiment defines a protection time where the charge pumping continues until a predefined phase is completed and the leakage paths are disabled. A third embodiment defines a phase memory block, which continues or remembers the phase until the next request for charge pumping. This prevents the circuitry from entering a window where charge leakage, which diminishes charge pumping efficiency, could occur.

Abstract: This invention provides a circuit layout pattern and layout method for matching pairs of metal oxide semiconductor field effect transistors used in matched pairs in precision analog circuits. The layout uses dummy Metal oxide field effect transistors, or MOSFETs, to keep the environment the same around each of the MOSFETs in a matched pair. The MOSFETs in a matched pair are in a single row with each MOSFET in the matched pair having dummy MOSFETs adjacent to it on either side. The dummy MOSFETs can be part of the matched pair, can be used in other parts of the circuit, or may not be used. The use of dummy MOSFETs keeps the environment around each MOSFET in the matched pair the same and this improves the matching characteristics.

Abstract: Capacitor arrays may be incorporated within silicon integrated circuits as part of analog-to-digital or digital-to-analog converters. Capacitance ratios between individual capacitors need to be controlled to better than 1%. Because of microloading effects during etching, the areas of the electrodes of the capacitors located along the edges of the array have tended to be slightly less than the areas of electrodes located completely inside the array. The present invention solves this problem by providing additional electrodes located along the periphery of the array, spaced the same distance away from the array edge as the spacing between electrodes inside the array.

Abstract: A method for making a polycide-to-polysilicon capacitor having an improved breakdown voltage is described. A first layer of doped polysilicon is formed over a silicon substrate. A silicide layer is formed over the first layer of doped polysilicon. An oxide layer is formed over the silicide layer, and the silicide layer is then annealed. A second layer of doped polysilicon is formed over the oxide layer. The second layer of doped polysilicon is patterned to form a top plate of the capacitor. The oxide layer is removed except under the top plate of the capacitor, where it acts as a capacitor dielectric. The first layer of doped polysilicon and the silicide layer are patterned to form a polycide bottom plate of the capacitor.
