ABSTRACT:
Embodiments of the disclosure include multilevel memory cell devices that utilize reference point cells to determine the states of other cells. Embodiments of the disclosure also include methods of storing data to and retrieving data from multilevel memory cell devices utilizing reference point cells. In one embodiment, a multilevel memory cell device includes user data cells, a reference point cell, and a controller. The user data cells each has one of a plurality of states. The reference point cell has a first state. The controller determines the states of the user data cells based at least in part on the first state of the reference point cell.
