Abstract
A memory array comprises N+1 memory elements. N memory elements store data and one or more error check bits respectively derived from the stored data. A separate N+1 memory element stores parity bits generated from the data stored in the N memory elements. These parity bits are stored in. To recover from data errors, data in each N memory element are first checked using their respective error check bits. If faulty data are detected in one of the N memory elements, an exclusive-or operation is performed involving data in the remaining N−1 memory elements and parity bits in the N+1 memory element. This recovers the faulty data in the one memory element.
