Abstract
Example memory devices, memory systems, and methods for reducing program disturb in NAND flash memory are disclosed. One example method includes applying, at a first time and during a channel preparation period of a program operation of a first memory cell in a memory cell array, a first voltage to a first word line coupled to the first memory cell. A second voltage is applied to the first word line at a second time after the first time and during the channel preparation period, where the second voltage is lower than the first voltage. A programming voltage is applied to the first word line after the channel preparation period and during the program operation of the first memory cell.
