Abstract
A method for correcting read data error of a nonvolatile memory device, the error correction method including performing a first read operation of applying a first non-selection read voltage to a plurality of unselected memory cells to read a plurality of selected memory cells, performing a second read operation of applying a second non-selection read voltage less than the first non-selection read voltage to the unselected memory cells to read the selected memory cells, and comparing data sensed in the first and second read operations to detect error locations of read data.
