Abstract
A memory device comprising: a memory cell array and a memory controller configured to program data to memory cells during a programming cycle using operations comprising: during a setup stage, providing a first voltage level to word lines, a second voltage level to a first dummy word line, and a fourth voltage level to second dummy word lines being different from the first dummy word line, wherein the first voltage level is lower than a threshold voltage of a first transistor coupled to the first dummy word line and the second voltage level and the fourth voltage are higher than the threshold voltage, during a program stage, providing a third voltage level to first word lines to program data to memory cells coupled to the first word lines, the second voltage level to the first dummy word line, and the fourth voltage level to the second dummy word lines.
