Abstract:
Apparatuses and techniques are described for reducing charge loss in a select gate transistor in a memory device. In one aspect, a refresh operation is performed repeatedly to couple up data word line voltages but not dummy word line voltages. The refresh operation can involve applying a voltage pulse to the data word lines of a block when the block is not being used for a storage operation such as a program, read or erase operation. When the voltage pulse is applied to the data word lines, the dummy word lines can be set to a low level such as 0 V. This low level prevents or limits coupling up of the dummy memory cells to avoid creating an electric field which can cause holes to move from the dummy memory cells to adjacent select gate transistors.

Claim (Index 15):
An apparatus, comprising:\n a selected block comprising memory cells, the memory cells arranged in NAND strings and connected to a set of word lines comprising data word lines and a dummy word line; means for applying a voltage pulse to the data word lines followed by floating of voltages of the data word lines, the applying of the voltage pulse followed by the floating of the voltages occurs repeatedly; and means for grounding a voltage of the dummy word line during the application of the voltage pulses.
