Abstract:
Apparatuses and techniques are described for programming memory cells with a narrow threshold voltage (Vth) distribution in a memory device. In one approach, the final pass of a multi-pass program operation on a word line WLn includes applying a variable voltage to WLn+1 during verify tests on WLn. The variable voltage (Vread) can be an increasing function of the verify voltage on WLn, and thus a function of the data state for which the verify test is performed. In one approach, Vread on WLn+1 is stepped up with each increase in the verify voltage on WLn. The step size in Vread can be the same as, or different than, the step size in the verify voltage. Vread can be different for each different verify voltage, or multiple verify voltages can be grouped for use with a common Vread.

Claim (Index 9):
The apparatus of  claim 6 , wherein:\n the multi-pass program operation comprises a first pass for the selected word line in which the memory cells of the selected word line are programmed to offset voltages below final states, followed by a first pass for the first adjacent word line in which memory cells of the first adjacent word line are programmed to the offset voltages below the final states, followed by a second pass for the selected word line in which the memory cells of the selected word line are programmed from the offset voltages to the final states, followed by a second pass for the first adjacent word line in which the memory cells of the first adjacent word line are programmed from the offset voltages to the final states.
