Claim 16:
17. A method of operating a storage device for performing a read operation of reading data stored in selected memory cells connected to a selected word line among a plurality of word lines included in a target memory block among a plurality of memory blocks, the method comprising:
applying a pass voltage to word lines adjacent to the selected word line;
discharging the pass voltage to a target pass voltage less than the pass voltage;
sensing a potential of bit lines connected to the selected memory cells connected to the selected word line after the pass voltage is discharged to the target pass voltage and a target read time elapses; and
determining whether the read operation has passed or failed by comparing the number of error bits of read data with the number of correctable error bits with respect to the selected memory cells.
