  • Patent number: 11122286
    Abstract: The present disclosure relates to motion vector determination using template matching. In particular, an initial motion vector and a template are obtained for a prediction block. Then a refinement of the initial motion vector is determined by template matching with said template in a search space. The search space is located on a position given by the initial motion vector. The template matching accesses integer sample positions within a predetermined window, the predetermined window including said search space and further integer sample positions accessible for the template matching, replaces at least one integer sample position located out of the window by at least one replacement value, each replacement value is based on at least one sample within said window, and uses the accessed integer sample position values as well as the at least one replacement value to perform the template matching.

  • Patent number: 11122292
    Abstract: A motion vector determination employs template matching. At first, an initial motion vector is obtained. If the initial motion vector points to a position that is fractional, and thus, requires interpolation from the integer sample positions, the initial motion vector is rounded to a closest integer sample position. The rounded position is then used to define the search space for the template matching to define a refinement of the initial motion vector.

  • Patent number: 10847234
    Abstract: A technique for read or program verify (PV) operations for non-volatile memory is described. In one example, at the end of a program verify operation (e.g., during a program verify recovery phase), a number of wordlines near a selected wordline are ramped down one at a time. Ramping down wordlines near the selected wordline one at a time can significantly reduce the trapped charge in the channel, enabling lower program disturb rates and improved threshold voltage distributions. In one example, the same technique of ramping down wordlines near the selected wordline can be applied to a read operation.
