  • Publication number: 20130002283
    Abstract: A method can be used for detecting defects in an electronic integrated circuit that includes a power input and a data input. The electronic integrated circuit is powered with a periodic power signal having a frequency and an input signal is applied to the data input. A surface of the electronic integrated circuit is swept with a laser beam. A first image is generated using a laser beam reflected from the surface and a second image is generated using a selected part of the laser beam reflected from the surface. The selected part of the reflected laser beam has a frequency that corresponds to the frequency of the power signal. Defects in the integrated circuit can be detected by superposing the first image and the second image.

  • Publication number: 20130002957
    Abstract: Aspects of the invention are directed towards an apparatus and method for detecting local video pixels in mixed cadence video. The local video detector comprises a comb detector that is adaptive to the contour of moving objects and local contrast, a motion detector that is robust to false motion due to vertical details, and a fader value estimator that provides a video confidence value to a fader that combines film mode and video mode processing results. The coupling of the local video detector to a film mode detector increases the robustness, accuracy, and efficiency of local film/video mode processing as compared to the prior art.

  • Publication number: 20130003462
    Abstract: A nonvolatile memory device includes a discharge circuit configured to selectively connect circuit nodes to discharge terminals through corresponding discharge paths, and an accumulation device for accumulating electric charge. A driving circuit is for driving the discharge circuit in such a way to connect at least a part of such circuit nodes to the discharge terminals if the value of the external supply voltage falls below a corresponding threshold. A supply circuit is for supplying the driving circuit with an intermediate supply voltage. Each one of the intermediate supply voltages is the corresponding external supply voltage when the value of the external supply voltage is higher than the corresponding threshold, or it is an internal voltage locally generated by the supply circuit by exploiting the electric charge stored by the accumulation device when the value of the external supply voltage is lower than the corresponding threshold.

  • Publication number: 20130007365
    Abstract: The approach is for protecting a solid state memory including a microprocessor. The microprocessor controls the requests for access to the physical blocks of the memory and transfers one or more requested files from a requesting device only subsequently to a comparison of a predetermined sequence of requests for access to the physical blocks. The predetermined sequence of requests for access to physical blocks corresponds to a predetermined sequence of requests for access to file(s) of the memory that can be selected by the device. If the sequence of requests for access does not occur, the microprocessor does not transfer the data requested or transfers them in a non readable format, for example in cryptographic form.

  • Publication number: 20130002224
    Abstract: A boost converter circuit receives an input power supply voltage and produces an output boosted supply voltage. The circuit includes a voltage regulator, boosting circuitry, and a timing controller. The voltage regulator provides a regulated voltage to the boosting circuitry, which controls switching a transistor to drive the output boosted supply voltage; and the timing controller controls switching the boost circuit from the start-up mode to the normal operation mode. In start-up mode, the regulated voltage is generated from the input power supply voltage. During normal operation mode, the regulated voltage is generated from the output boosted supply voltage. The circuitry performs a low-power start-up when the input power supply voltage is low, and maintains efficient low-power operation by driving the transistor to produce the output boosted supply voltage as the input power supply voltage decreases.

  • Publication number: 20130002365
    Abstract: A crystal oscillator circuit is configured to output an oscillation signal. A bias circuit responds to control signal to generate a bias current for application to the crystal oscillator circuit. A current generator generates a sense current from the control signal. The sense current is compared to a reference current by a comparator circuit. The comparator circuit generates a ready signal in response to the comparison. The ready signal is indicative of whether the oscillation signal output from the crystal oscillator circuit is ready for use by other circuitry. The reference current may be generated by a circuit which replicates the bias circuit.
