Abstract

Control logic in a memory device causes a pass voltage to be applied to a plurality of wordlines of a block of a memory array of the memory device, the block comprising a plurality of sub-blocks, and the pass voltage to boost a channel potential of each of the plurality of sub-blocks to a boost voltage. The control logic further selectively discharges the boost voltage from one or more of the plurality of sub-blocks according to a data pattern representing a sequence of bits to be programmed to respective memory cells of the plurality of sub-blocks. In addition, the control logic causes a single programming pulse to be applied to a selected wordline of the plurality of wordlines of the block to program the respective memory cells of the plurality of sub-blocks according to the data pattern.
