Abstract:
Apparatuses and techniques are described for reducing charge loss in a select gate transistor in a memory device. In one aspect, a dummy memory cell adjacent to a select gate transistor is weakly programmed during an erase operation by applying a program pulse to the dummy memory cell. The program pulse can be applied after an erase bias is applied to the memory cells and before an erase-verify test is performed, in one approach. The program pulse can be applied during the setup of the voltages for the erase-verify test. The magnitude of the program pulse can be increased in successive erase loops of an erase operation as the magnitude of a substrate voltage is also increased. The magnitude of the program pulse can also be set as an increasing function of a number of program-erase (P-E) cycles.

Claim (Index 9):
The apparatus of  claim 1 , wherein:\n the program circuit, to apply the program bias, is configured to request in a clock cycle that a voltage driver increase a control gate voltage of the dummy memory cell from an initial level to an intermediate level and request in another, subsequent clock cycle that the voltage driver increase the control gate voltage from the intermediate level to a peak level.
