Abstract
A Bose-Chaudhuri-Hocquenghem (BCH) error correction circuit and method including storing normal data and first parity data in a memory cell array, the normal data and first parity data forming BCH encoded data; generating second parity data from the stored normal data; comparing the first parity data with the second parity data; and checking for an error in the normal data in response to the comparing.
