Abstract:
Techniques are provided for reducing program disturb in a 3D memory device. The techniques include compensating for a temperature dependence of program disturb. The techniques may include compensating for how program disturb depends on the location of the word line that is selected for programming. In one aspect, the voltage that is applied to the control gates drain side select transistors of unselected NAND strings is adjusted during programming based on temperature. Greater temperature compensation may be applied when the selected word line is closer to the drain side select transistors.
