摘要： Memory devices are configured to store a number of access line biasing patterns to be applied during a memory device operation performed on a particular row of memory cells in the memory device. Memory devices are further configured to support modification of the stored bias patterns, providing flexibility in biasing access lines through changes to the bias patterns stored in the memory device. Methods and devices further facilitate performing memory device operations under multiple biasing conditions to evaluate and characterize the memory device by adjustment of the stored bias patterns without requiring an associated hardware change to the memory device.

摘要： 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.
