Abstract
A memory device includes a cell array including a plurality of pages and a control logic configured to control program and read operations of the cell array. The control logic controls the program and read operations to store first through N-th codewords in a first page among the pages and program a page parity corresponding in common to the first through N-th codewords to the first page in response to a program command for a page unit and to selectively read the first codeword among the first through N-th codewords in response to a read command for a sub-page unit, where N is an integer of at least 2. The first codeword includes first sub-page data and a first sub-parity corresponding thereto, and the first sub-parity includes information for correcting an error in the first sub-page data through error correction code (ECC) decoding independently performed on each codeword.
