Abstract
A non-volatile storage system comprises memory cells arranged in groups of memory cells that include programmable select gates and one or more control circuits in communication with the memory cells. The one or more control circuits configured to identify a select gate that needs to be programmed and program the select gate identified to be programmed if a temperature at the non-volatile memory cells is greater than a minimum temperature and defer programming of the select gate identified to be programmed until the temperature at the non-volatile memory cells is greater than the minimum temperature. In some embodiments, the one or more control circuits are configured to perform dummy memory operations on the plurality of non-volatile memory cells to raise the temperature of the non-volatile memory cells in response to determining that the temperature at the non-volatile memory cells is not high enough.
