Abstract
A storage device is disclosed. The storage device is configured to: determine data states for a first set of memory cells of a first neighboring word line of the and a second set of memory cells of a second neighboring word line, the first and the second neighboring word lines being adjacent to a selected word line; identify a zone of a plurality of zones for each data state combination of the data states, each data state combination comprising a data state of a memory cell of the first set of memory cells and a data state of a memory cell of the second set of memory cells, each zone of the plurality of zones corresponding to a data retention compensation scheme; and perform a read operation on the selected word line including applying each data retention compensation scheme corresponding to any zones identified.
