  • Patent number: 12207466
    Abstract: In a method for fabricating a semiconductor device, an initial stack of alternatingly sacrificial word line layers and insulating layers is formed over a substrate of the semiconductor device. A connection region, a first staircase region, and a second staircase region are patterned in the initial stack. The first staircase region is shaped in the initial stack to form a first staircase, and the second staircase region is shaped in the initial stack to form a second staircase. The first staircase is formed in a first block of the initial stack and extends between first array regions of the first block. The second staircase is formed in a second block of the initial stack and extends between second array regions of the second block. The connection region is formed in the initial stack between the first staircase and the second staircase.

  • Patent number: 12183043
    Abstract: A computing system may access first alpha values associated with first pixels in a first pixel region of an image and determine a bit budget for encoding the first alpha values. The computing system may then select a first alpha-encoding mode for the first alpha values to reflect a determination that the first alpha values are all fully transparent or all fully opaque, and encode the first alpha values by storing the selected first alpha-encoding mode as part of a metadata without using the bit budget to encode the first alpha values individually. The computing system may then update a record of unallocated bits available for allocation based on the bit budget unused in the encoding of the first alpha values, and allocate, based on the record of unallocated bits, bits to encode a set of alpha values different from the first alpha values.
