Abstract: Methods, systems, and devices for non-destructive pattern identification at a memory device are described. A memory device may perform pattern identification within the memory device and output a flag indicating whether a first data pattern matches with a second data pattern. The memory device may access one or more memory cells, via a word line, and latch the second data pattern of the memory cells to a sense amplifier. The memory device may deactivate the word line, which may result in isolating the memory cells from potential destruction of data. The memory device may write a first data pattern to the sense amplifier and compare the first data pattern and second data pattern at the sense amplifier. The memory device may output a signal indicating whether the data patterns match.

Abstract: The present disclosure provides a display motherboard, a method for fabricating the same, and a method for aligning the same. The display motherboard includes an array substrate on which an alignment mark and a color film layer are provided. A portion of a black matrix of the color film layer in an alignment mark area includes a first light-shielding portion and a second light-shielding portion.

When the display motherboard is aligned in the subsequent processes, since the black matrix forms the same pattern as the alignment mark due to a height step, when the exposure machine exposures, the pattern can be directly captured for alignment.

Abstract: Embodiments of the disclosure are drawn to apparatuses, systems, and methods for dynamic targeted refresh steals. A memory bank may receive access commands and then periodically enter a refresh mode, where auto refresh operations and targeted refresh operations are performed. The memory bank may receive a refresh management command based on a count of access commands directed to the memory bank. Responsive to the refresh management signal, a panic targeted refresh operation may be performed on the memory bank. A number of times the refresh management signal was issued may be counted, and based on that count a next periodic targeted refresh operation may be skipped.

Abstract: A dynamic random access memory employs either or both of a normal row copy operation or a fast row copy operation to copy selected data from a first row of memory to a second row of memory, without transferring the data to an intermediary processor such as a central processing unit or a memory controller. Both operations depend on a concurrent electrical activation of two separate wordlines within a bank of a DRAM. For the fast row copy operation, the two separate wordlines are part of a shared section of a DRAM bank, having shared bitlines. Bit values are copied directly in parallel via common bitlines. For the normal row copy operation, the two separate wordlines are part of a common bank but not a shared section. Bit values are copied in serial via a general input/output bus within the bank.

Abstract: A system and method for video compression divides colors of all pixel points of a target video frame into R, G, and B values, and all pixels are placed in a three-dimensional coordinate system to establish a correspondence between each pixel point and the coordinate position. Fuzzy recombination and division are performed on all pixel blocks and pixel points with similar RGB values are divided into pixel blocks to obtain a first target pixel block. Pixel blocks with same RGB values but with coordinates which are not close to the first target pixel block are extracted and divided to obtain a second target pixel block. An area enveloping the second target pixel block is extracted, and vector changes of all dynamic pixel points on the enveloping line are traversed and analyzed to determine a minimum compression change block for compression process.
