Abstract
The non-volatile memory includes a control circuitry that is communicatively coupled to an array of memory cells that are arranged word lines. The control circuitry is configured to program the memory cells using a multi-pass programming operation which includes a first pass and a second pass. The first pass programs the memory cells to a first number of data states, and the second pass programs the memory cells to a greater second number of data states. For at least one word line, during the second pass, a voltage that is applied to at least one memory cell is reduced from a verify voltage by an offset which is determined as a function of a data state of an adjacent memory cell of an adjacent word line and wherein the first pass but not the second pass has been completed in the adjacent word line.
