    Abstract: Control logic in a memory device receives a request to program data to a block of a memory array of the memory device, the block comprising a plurality of sub-blocks, and identifies a first sub-block of the plurality of sub-blocks to be programmed with at least a portion of the data. The control logic further causes a plurality of control signals to be applied to a plurality of logical select gate layers positioned at a drain-side of the block to activate the first sub-block, and causes a program signal to be applied to a selected wordline of the block to program at least the portion of the data to a memory cell in the first sub-block and associated with the selected wordline.

    Abstract: A memory device stores data in non-volatile memory. The memory device includes a non-volatile memory array. The memory array includes tiers for accessing data stored in blocks of the memory array, including a block having a left block portion and a right block portion. A first staircase is positioned between the left block portion and the right block portion, and a bottom portion of the first staircase includes steps corresponding to first tiers of the left block portion. A second staircase is positioned between the left block portion and the right block portion, and a top portion of the second staircase includes steps corresponding to second tiers of the right block portion. The steps of the first staircase and the steps of the second staircase descend in opposite directions.
