Abstract
Technology for two-sided adjacent memory cell interference mitigation in a non-volatile storage system is disclosed. During reading of target memory cells, the storage system applies a suitable magnitude read pass voltage to a first unselected word line adjacent to a target word line to compensate for interference from adjacent cells on the first unselected word line while applying a suitable magnitude read reference voltage to the target word line to compensate for interference from adjacent cells on a second unselected word line on the other side of the target word line. The read pass voltage may compensate for interference due to charge being added to when programming cells on the first unselected word line after programming the target cells. The read reference voltage may compensate for interference due to charge movement near the target cells that results from charge stored in the cells on the second unselected word line.
