PRE-BOOSTING SCHEME DURING A PROGRAM OPERATION IN A MEMORY SUB-SYSTEM

Abstract:

Control logic in a memory device initiates, subsequent to a program verify phase of a program operation, a new program operation on the memory array, the new program operation comprising a pre-boosting phase occurring prior to a program phase. The control logic causing one or more positive pre-boosting voltages to be applied to corresponding subsets of a plurality of word lines of a block of the memory array during the pre-boosting phase and causes the one or more positive pre-boosting voltages to be ramped down to a ground voltage during the pre-boosting phase in a designated order based on a location of the corresponding subsets of the plurality of word lines to which the one or more positive pre-boosting voltages were applied.
