  • Patent number: 6998143
    Abstract: An iron fortification complex which may be used to fortify foods and beverages with iron. The complex is formed of ferric ions and caseinate. The complex is sufficiently stable as to be suitable for use in retorted products. However, despite the stability, the iron in the complexes has substantially the same bioavailability as ferrous sulfate.

  • Patent number: 6999918
    Abstract: A dictionary is comprised of a dendroid hierarchy of branches and nodes, wherein each node represents no more than one symbol (which symbol is to be converted to a corresponding sound) and wherein each such symbol as is represented at a given node has only one corresponding sound associated with that symbol at that node. In addition, many of the branches include a plurality of nodes representing a string of the symbols in a particular sequence. The dictionary is used to translate an input comprising a given integral sequence of the symbols into a corresponding integral sequence of sounds. This permits both method and apparatus to convert, for example, text to representative phonemes. Such phonemes can be used, amongst other purposes, to support synthesized speech production.

  • Publication number: 20050250278
    Abstract: Methods and structures are presented for protecting flash memory wordlines and memory cells from process-related charging during fabrication. Undoped polysilicon is formed at the ends of doped polysilicon wordlines to create resistors through which process charges are discharged to a doped polysilicon discharge structure coupled with a substrate. The wordlines, resistors, and the discharge structure can be formed as a unitary patterned polysilicon structure, where the wordline and discharge portions are selectively doped to be conductive and the resistor portions are substantially undoped to provide a resistance high enough to allow normal cell operation after fabrication while providing a discharge path for process-related charging during fabrication.

  • Patent number: 6934190
    Abstract: Methods of operating dual bit memory devices including programming with a range of values are provided. The present invention employs a range of ramp source program pulses to iteratively perform a program operation that employs hot hole injection. The range is related to channel lengths of individual dual bit memory cells within the memory device. To program a bit of a particular dual bit memory cell, a negative gate program voltage is applied to its gate, a positive drain voltage is applied to its acting drain, and its substrate is connected to ground. Additionally, a ramp source voltage of the range of ramp source program pulses is concurrently applied to an acting source of the dual bit memory cell. A verification operation is then performed and the programming is repeated with a decremented ramp source voltage on verification failure.

  • Publication number: 20050153508
    Abstract: A technique for forming at least part of an array of a dual bit memory core is disclosed. Initially, a portion of a charge trapping dielectric layer is formed over a substrate and a resist is formed over the portion of the charge trapping dielectric layer. The resist is patterned and a pocket implant is performed at an angle to establish pocket implants within the substrate. A bitline implant is then performed to establish buried bitlines within the substrate. The patterned resist is then removed and the remainder of the charge trapping dielectric layer is formed. A wordline material is formed over the remainder of the charge trapping dielectric layer and patterned to form wordlines that overlie the bitlines. The pocket implants serve to mitigate, among other things, complementary bit disturb (CBD) that can result from semiconductor scaling. As such, semiconductor devices can be made smaller and increased packing densities can be achieved by virtue of the inventive concepts set forth herein.

  • Patent number: 6900085
    Abstract: One aspect of the present invention provides a process for forming IC devices with ESD protection transistors. According to one aspect of the invention, an ESD protection transistor is provided with a light doping and then, after forming spacers, a heavy doping. The heavy doping with spacers in place can lower the sheet resistance, enhance the bipolar effect for the transistor, reduce the transistor's capacitance, and reduce the junction breakdown voltage, all without causing short channel effects. The invention thereby provides ESD protection transistors that are compact, highly sensitive, and fast-switching. The spacers can be formed at the same time as spacers for other transistors, such as other transistors in a peripheral region of the device.
