Abstract:
The memory device includes a memory block, which includes a plurality of memory cells arranged in a plurality of word lines. The memory device also includes control circuitry in communication with the memory block. The control circuitry is configured to perform a programming operation to program the memory cells of a selected word line of the plurality of word lines. During the programming operation, the control circuitry is configured to apply a programming pulse VPGM to a selected word line to the selected word line, apply a first pass voltage to a first set of word lines of the plurality of word lines, the first set of word lines being adjacent the selected word line, and apply a second pass voltage to a second set of word lines of the plurality of word. The first pass voltage is greater than the second pass voltage.
