Abstract: Systems, methods, and apparatus related to memory devices. In one approach, a cross-point memory array includes memory cells. A media controller reads one or more first memory cells and determines a read status. The read status indicates an error when reading the first memory cells. In response to this error, the controller refreshes the first memory cells. The controller uses the read status to determine zero-to-one failures associated with the first memory cells. If a number of these failures exceeds a threshold, then a refresh is applied to neighboring memory cells of the first memory cells. The physical addresses for the neighboring memory cells are determined by the controller from the physical addresses for the first memory cells.
