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 12):
A method, comprising:\n sensing a data memory cell in a set of connected memory cells in a selected block of a memory device, the set of connected memory cells also comprising a dummy memory cell, the dummy memory cell positioned adjacent to a select gate transistor, the memory device also comprising a set of connected memory cells in an unselected block, the set of connected memory cells in the unselected block comprising a data memory cell and a dummy memory cell, the dummy memory cell in the unselected block positioned adjacent to a select gate transistor in the unselected block; and during the sensing of the data memory cell in the selected block, applying a positive voltage to a control gate of the data memory cell in the unselected block, and applying a ground voltage to a control gate of the dummy memory cell in the unselected block.
