Claim 8:
9. A storage device comprising:
a nonvolatile memory device including a memory cell array connected to word lines;
a controller configured to provide a read command to control read operations of the nonvolatile memory device; and
a read level generator configured to generate an off-cell count value of memory cells from among the memory cell array that are connected to a first word line from among the word lines responsive to the read command indicative of a request to read a target memory cell from among the memory cells that are connected to a second word line from among the word lines, compare the off-set count value to a first reference count value of the first word line to provide a comparison result, and determine a read level for reading the target memory cell based on the comparison result,
wherein the first word line is adjacent to the second word line.
