    Abstract: PROBLEM TO BE SOLVED: To provide a digital matched filter in which power consumption is reduced, and a silicon area is reduced.
    SOLUTION: The digital matched filter receives an input signal in a natural order. That input signal is then correlated against a code to produce filtered output signals. The filtered output signals, however, are produced from the correlation in a permuted order with respect to the received input signal. The code is the factorized first and second patterns. The filter includes: first filters for correlation with respect to the first code; second filters for correlation with respect to the second pattern; and a memory for storing the intermediate values produced by the correlative operation of the first filters. Certain ones of the intermediate values are thereafter selectively retrieved from the memory in response to an unique addressing scheme with respect to the correlation operations of each second filter. In accordance with the scheme, the retrieved intermediate values are reused in succeeding second filtering correlations.

    Abstract: PROBLEM TO BE SOLVED: To provide technique for monitoring reference voltage generated in a semiconductor memory device to simplify memory access operation.
    SOLUTION: A pair of Schmitt trigger circuits are used. The first Schmitt trigger circuit detects that voltage appearing on an output of a reference voltage generator is dropped to a lower level than the minimum threshold voltage level. The second Schmitt trigger circuit detects that output voltage of the reference voltage generator exceeds the maximum threshold voltage level. This circuit can have a reset circuit giving initially the prescribed voltage level on an input of the Schmitt trigger circuit. The output circuit receives an output of each Schmitt trigger circuit and generates an output signal having a value indicating whether an output of the reference voltage generator is in a voltage range or not.

    Abstract: PROBLEM TO BE SOLVED: To mitigate dishing during chemical mechanical polishing of a conformal tungsten layer. SOLUTION: A protective barrier layer, composed of a material such as titanium or titanium nitride, is formed on a conformal tungsten layer. Removal of the protective barrier layer by chemical mechanical polishing(CMP) is primarily mechanical rather than chemical. During subsequent CMP to pattern the tungsten layer, upper topological regions of the protective barrier layer are removed first, and the tungsten under those regions are exposed to be removed, while protective barrier layer regions over lower topological regions remain to prevent chemical attack to the underlying tungsten.

    Abstract: PROBLEM TO BE SOLVED: To provide a spin-up wedge relative to the spin-up of a data storage disk and to provide an improved servo circuit and a method to detect a corresponding servo-wedge.
    SOLUTION: The servo circuit has a servo channel and a processor. The servo channel recovers servo data from a servo-wedge which identifies respective data sectors on the data storage disk. Relative to the spin-up of the disk, the processor detects a spin-up wedge related to one of the servo-wedge and then, detects the servo-wedge. When the servo-wedge is detected, a head positioning circuit reads positioning data from the servo-wedge and determines an initial position of a read/write head. By detecting both a spin-up wedge and a servo- wedge to determine the initial head position relative to a disk spin-up, the servo circuit frequently reduces the length of a spin-up wedge and increases the capacity of disk storage.

    Abstract: PROBLEM TO BE SOLVED: To improve the durability and reliability of a fingerprint detector.
    SOLUTION: The fingerprint detector having a smooth sensor surface for contact with a fingerprint includes capacitive sensor plates defining an array of sensor cells below the sensor surface and tungsten ESD protection grid lines surrounding each sensor cell. The sensor surface is defined by silicon carbide and includes silicon oxide filling cavities in the silicon carbide. The cavities inherently result from processing steps, including the removal of tungsten atop the silicon carbide that is used to define the grid lines. The cavities are filled with the oxide, and the surface made smooth by using chemical mechanical polishing, thus a scratch resistant surface is provided and the sensitivity of the capacitive sensor cells is improved.

A phase detector (720) compares phase between a first timing signal input (704) and the delay line output (706). A bias adjust circuit mixes the phase compare output signal (725) and the phase lock output signal (715), to provide a combination bias signal (727) to the delay line (702). Additionally, the relative timing position of strobe outputs (743) from the delay line (702) can be individually adjusted.
