  • Patent number: 11985906
    Abstract: A magnetic tunnel junction (MTJ) memory cell and a metallic etch mask portion are formed over a substrate. At least one dielectric etch stop layer is deposited over the metallic etch mask portion, and a via-level dielectric layer is deposited over the at least one dielectric etch stop layer. A via cavity may be etched through the via-level dielectric layer, and a top surface of the at least one dielectric etch stop layer is physically exposed. The via cavity may be vertically extended by removing portions of the at least one dielectric etch stop layer and the metallic etch mask portion. A contact via structure is formed directly on a top surface of the top electrode in the via cavity to provide a low-resistance contact to the top electrode.

  • Patent number: 11665340
    Abstract: A disclosed computer-implemented method may include (1) selecting, from a video stream, a reference frame and a current frame, (2) collecting a reference histogram of the reference frame and a current histogram of the current frame, and (3) generating a smoothed reference histogram by applying a smoothing function to at least a portion of the reference histogram. In some examples, the computer-implemented method may also include (1) determining a similarity metric between the smoothed reference histogram and the current histogram and, (2) when the similarity metric is greater than a threshold value, applying weighted prediction during a motion estimation portion of an encoding of the video stream. Various other methods, systems, and computer-readable media are also disclosed.

  • Publication number: 20230140628
    Abstract: A system that includes a pixel processing stage decoupled from an entropy coding stage is disclosed. The pixel processing results comprise quantized transform coefficients that are divided into component blocks. The component blocks including non-zero data are identified. An optimized version of the pixel processing results for storage in a buffer storage is generated. The optimized version includes an identification of which of the component blocks include non-zero data, and the optimized version includes contents of one or more of the component blocks that include non-zero data, without including contents of one or more of the component blocks that only include zero data. The optimized version of the pixel processing results is provided for storage in the buffer storage. The optimized version of the pixel processing results from the buffer storage is received and processed to generate an unpacked version of the pixel processing results for use in entropy coding.

  • Publication number: 20100257415
    Abstract: An instruction-based programmable memory built-in self test (P-MBIST) circuit and an address generator thereof are provided. The P-MBIST circuit generates control signals according to the decoding of compact test instructions provided by an external automatic test equipment (ATE). The address generator generates memory addresses according to the control signals. The control signals and the memory addresses are sent to an embedded memory to perform the MBIST. The algorithm-specific design of the P-MBIST circuit and the address generator enables them to support multiple test algorithms at full clock speed and occupy smaller chip area.
