Abstract
The memory device includes a memory block that has a plurality of memory cells that are arranged in a plurality of word lines and in a plurality of channels. The memory device also includes circuitry that is configured to conduct a hole pre-charge operation to inject holes into the plurality of channels. During the hole pre-charge operation, the circuitry applies a positive CELSRC pre-charge voltage to a source line of the memory block and applies a negative unselected word line pre-charge voltage to a plurality of unselected word lines in the memory block to make a plurality of memory cells in the memory block conductive to holes.
