Claim 2:
3. The non-volatile storage apparatus of claim 1, further comprising:
dummy memory cells; and
a dummy word line connected to the dummy memory cells, the dummy word line is positioned between the selected word line and the one or more control lines, the control circuit is configured to apply a first voltage to the dummy word line when pre-charging channels of unselected memory cells at the end of program-verify, the first voltage is greater than threshold voltages of the dummy memory cells, the control circuit is configured to cut off the channels of the unselected memory cells from the one or more control lines by lowering the dummy word line from the first voltage to a voltage that is lower than threshold voltages of the dummy memory cells.
