摘要:
The memory device includes at least one memory block with source and drain sides and a plurality of memory cells arranged in a plurality of word lines. The word lines are arranged in a plurality of independently programmable and erasable sub-blocks. Control circuitry is configured to program the memory cells of a selected sub-block and determine a location of the within the at least one memory block and determine a programming condition of at least one unselected sub-block. The control circuitry is also configured to program at least one word line in the selected sub-block in a plurality of program loops that include pre-charging processes. The control circuitry pre-charges a plurality of channels from either the source or drain side based on at least one of the location of the selected sub-block within the memory block and the programming condition of the at least one unselected sub-block.
