Abstract:
PROBLEM TO BE SOLVED: To provide a technique for replacing defective memory cells of a nonvolatile memory device according to the types of defects. SOLUTION: A method and circuit are disclosed for replacing defective columns of flash memory cells in a flash memory device. The circuit includes a plurality of sets of storage elements, each set of storage elements are capable of identifying a single addressed column of memory cells is to be replaced or a main column line and regular columns of memory cells associated therewith to be replaced. In the event a main column line and the associated regular columns are identified for replacement by a set of storage elements, the set additionally indicates whether the regular columns are regular columns in a single block of memory cells or multiple blocks. Redundancy circuitry performs the replacement operation during a memory access operation based upon the information stored in the sets of storage elements.

PROBLEM TO BE SOLVED: To improve a redundancy technique of a non-volatile memory device. SOLUTION: The technique is disclosed for replacing defective columns of flash memory cells in a flash memory device. The circuit includes a plurality of sets of storage elements, each set of storage elements are capable of identifying at least one column of memory cells in any block of memory cells as being defective. The circuit further includes control circuitry for replacing an addressed column of memory cells with a redundant column of memory cells upon an affirmative determination that a set of storage elements identify the addressed column of memory cells as being defective.
Abstract:
PROBLEM TO BE SOLVED: To provide a system and a method which make it possible to correct a driver at a faster rate. SOLUTION: A power driver for driving a signal on a load uses a voltage- mode driver. A system processor generates commands indicating a programmed drive signal desired from the voltage-mode driver. A lead compensator determines a compensated command to compensate for an admittance function of the load. The compensated commands are coupled to the voltage-mode driver, so that the voltage-mode driver generates a voltage output based upon the compensated command. COPYRIGHT: (C)2003,JPO

Abstract:
A method for forming contacts in a semiconductor device includes forming (208) a plurality of substantially parallel semiconductor fins on a dielectric layer of a substrate having a gate structure formed (210) transversely to a longitudinal axis of the fins. The fins are merged (212) by epitaxially growing a crystalline material between the fins. A field dielectric layer is deposited over the fins and the crystalline material. Trenches that run transversely to the longitudinal axis of the fins are formed (226) to expose the fins in the trenches. An interface layer is formed (228) over portions of the fins exposed in the trenches. Contact lines are formed (234) in the trenches that contact a top surface of the interface layer on the fins and at least a portion of side surfaces of the interface layer on the fins.
Abstract:
In an embodiment, to deter or delay counterfeiting/cloning of a replacement component of a host device, the replacement component is provided with a code value. The code value is generated from a value of at least one physical parameter of the replacement component and is stored on the replacement component. The host device determines whether the replacement component is authentic if the stored code value matches a reference code value.
Abstract:
The substrate successively comprises a support substrate, an electrically insulating layer, a semiconductor material layer, and a gate pattern. The semiconductor material layer and gate pattern are covered by a covering layer. A first doping impurity is implanted in the semiconductor material layer through the covering layer so as to place the thickness of maximum concentration of the first doping impurity in the first layer. The covering layer is partly eliminated so as to form lateral spacers leaving source/drain electrodes free.

The foregoing apparatus and methods can be applied to any RF signal application (wireless or otherwise), including for example wireless cellular handsets.
Abstract:
Improved interpolator and decimator apparatus and methods, including the addition of an elastic storage element in the signal path. In one exemplary embodiment, the elastic element comprises a FIFO which advantageously allows short term variation in sample clocks to be absorbed, and also provides a feedback mechanism for controlling a delta-sigma modulated modulo-N counter based sample clock generator. The elastic element combined with a delta-sigma modulator and counter creates a noise-shaped frequency lock loop without additional components, resulting in a much simplified imterpolator and decimator.
