Abstract
A nonvolatile memory device includes a nonvolatile memory, a buffer memory configured to store a plurality of read data transmitted from the nonvolatile memory, an error detection and correction circuit configured to detect an error in partial data of each of the plurality of read data and judging whether the partial data is correctable or not on the basis of the detected error, and a controller configured to analyze the uncorrectable partial data with respect to the plurality of read data to determine a representative value, and to transmit the representative value to the error detection and correction circuit. The plurality of read data is read through a read operation with respect to a same page.
