    Abstract: Systems, methods, and devices are described herein for integrated circuit (IC) layout validation. A plurality of IC patterns are collected which include a first set of patterns capable of being manufactured and a second set of patterns incapable of being manufactured. A machine learning model is trained using the plurality of IC patterns. The machine learning model generates a prediction model for validating IC layouts. The prediction model receives data including a set of test patterns comprising scanning electron microscope (SEM) images of IC patterns. Design violations associated with an IC layout are determined based on the SEM images and the plurality of IC patterns. A summary of the design violations is provided for further characterization of the IC layout.

  • Patent number: 9905277
    Abstract: A memory system comprises a memory controller and a memory device having one or more memory ranks and multiple memory electrically connected to the one or more memory ranks. The memory controller includes at least one analysis module and at least one switching determination module. The analysis module analyzes states of multiple memory control commands corresponding to a particular memory rank to generate a control parameter. The switching determination module determines whether at least one switching command is sent according to the control parameter, a current operation mode of the particular memory rank, and an operation state of the particular memory rank. When the memory device receives a first switching command of the at least one command, the particular rank and at least one part of the memory internal circuits are switched from the normal voltage operation mode to the low voltage operation mode.

  • Patent number: 8531199
    Abstract: The method and circuit for testing a TSV of the present invention exploit the electronic property of the TSV under test. The TSV under test is first reset to a first state, and is then sensed at only one end to determine whether the TSV under test follows the behavior of a normal TSV, wherein the reset and sense steps are performed at only one end of the TSV under test. If the TSV under test does not follow the behavior of a normal TSV, the TSV under test is determined faulty.

    Abstract: A multiplication circuit generates a product of a matrix and a first scalar when in matrix mode and a product of a second scalar and a third scalar when in scalar mode. The multiplication circuit comprises a sub-product generator, an accumulator and an adder. The adder is configured to sum outputs of the accumulator to generate the product of the first scalar second scalar and the third scalar when in scalar mode. The sub-product generator generates sub-products of the matrix and the first scalar when in matrix mode and sub-products of the second scalar and the third scalar when in scalar mode. The accumulator is configured to generate the product of the matrix and the first scalar by providing save of the multiplication operation of the outputs from the sub-product generator.
