Abstract
A memory device includes one or more memory arrays and a quad bit error correction circuit. The quad bit error correction circuit may include a first layer error correction circuit and a second layer error correction circuit. The first layer error correction circuit may be configured to generate a Hamming correction bit vector, and the second layer error correction circuit may be configured to generate a Golay correction bit vector. The Hamming correction bit vector and the Golay correction bit vector may be used to identify up to four correctable bit errors in data to be stored in the one more memory arrays.
