  • Patent number: 7093171
    Abstract: A row redundancy system is provided for replacing faulty wordlines of a memory array having a plurality of banks. The row redundancy system includes a remote fuse bay storing at least one faulty address corresponding to a faulty wordline of the memory array; a row fuse array for storing row fuse information corresponding to at least one bank of the memory array; and a copy logic module for copying at least one faulty address stored in the remote fuse bay into the row fuse array; the copy logic module is programmed to copy the at least one faulty address into the row fuse information stored in the row fuse array corresponding to a predetermined number of banks in accordance with a selectable repair field size.

  • Patent number: 7057866
    Abstract: An integrated circuit system having a plurality of macros is provided. The integrated circuit system includes an external voltage supply input configured for supplying an external voltage to the integrated circuit; and a plurality of internal voltage supply generators, each of the plurality of internal voltage supply generators being connected to a respective macro of the plurality of macros and configured for receiving the external voltage via the external voltage supply input for generating an internal voltage supply for operating its respective macro. Each of the plurality of internal voltage supply generators includes circuitry for generating the internal voltage supply and circuitry for disconnecting at least a portion of its respective macro. The integrated circuit system can be applied to a semiconductor chip to save active or stand-by power. It can also be used to disconnect a defective portion of the chip and optionally replace it with a non-defective portion of the chip.

  • Patent number: 6993535
    Abstract: This invention is a business system and method to perform categorization (classification) of multimedia items and to make business decisions based on the categorization of the item. The multimedia items are comprised of a multitude of disparate information sources, in particular, visual information and textual information. Classifiers are induced based on combining textual and visual feature vectors. Textual features are the traditional ones. Visual features include, but are not limited to, color properties of key intervals and motion properties of key intervals. The visual feature vectors are determined in such a fashion that the vectors are sparse. The text and the visual representation vectors are combined in a systematic and coherent fashion. This vector representation of a media item lends itself to well-established learning techniques and can be used for multimedia item categorization. The resulting business system, subject of this invention, can be used for many purposes.

  • Patent number: 6990008
    Abstract: A device (2) with a switchable capacitance comprises a first and a second electrode (12, 20) facing each other, a dielectric layer (14) between a first and a second capacitor electrode (12, 20), and a switching member (18) between the second electrode (20) and the dielectric layer (14), the switching member (18) comprising a switching material reversibly switchable between a lower conductivity state and a higher conductivity state, each of the lower conductivity state and the higher conductivity state being persistent, wherein the capacitance of the device (2) depends on the conductivity state of the switching material.

  • Patent number: 6978446
    Abstract: A method for changing an operation performed by an electronic device includes defining a process flow chart of the operation to be performed by the electronic device, the process flow chart having one or more primitive actions, the operation having one or more components, the primitive action operating on the components to produce an output. The method further includes determining a number of information dispersal units for each of the components. For each of the components, defining a set of information dispersal units, transforming one or more of the primitive actions of the operation using a transform function to create a transformed primitive action, and applying each of the transformed primitive actions to all the respective sets of information dispersal units to produce a transformed set of transformed information dispersal units.
