Abstract
A method of operating a memory device includes reading a first page of memory cells containing at least one worn-out memory cell therein using a read voltage, from a first memory block, and reading a second page of memory cells, which extends adjacent to the first page in the first memory block, using the read voltage. An operation is performed to determine a match rate between a position of a column including a '0' bit in the first page with a position of a column including a “0” bit in the second page. Thereafter, the second page is read by adjusting a read pass voltage applied to a word line of another page in the first memory block, when the match rate exceeds a threshold match rate.
