Abstract
A data recover read (DRR) operation method of a nonvolatile memory system includes: performing a first read operation on adjacent memory cells, which are connected to an adjacent wordline adjacent to a target wordline, based on a first specific read level; obtaining a cell count value for the adjacent wordline; determining offset values for a normal read level of target memory cells, which are connected to the target wordline, based on the cell count value for the adjacent wordline; and performing a second read operation on the target memory cells, based on the determined offset values and a result of the first read operation.
