Abstract
A data storage device including, in one implementation, a non-volatile memory and a controller. The non-volatile memory includes a memory block. The memory block includes a plurality of word lines that are written sequentially from a first end of the memory block to a second end of the memory block. The controller is coupled to the non-volatile memory. The controller is configured to determine a last written word line of the memory block. The controller is also configured to set a non-selected word line voltage based on the last written word line of the memory block. The controller is further configured to apply the non-selected word line voltage to non-selected word lines of the memory block.
