Abstract
To improve the reliability of a memory system, data and error correction codes associated with the data can be stored in a first memory. Parity bits calculated over data bits in the first memory can be stored in a second memory. The parity bits in the second memory can be used to recover errors that are uncorrectable by the error correction codes. The first memory can be implemented, for example, using an emerging memory technology, while the second memory can be implement using a different memory technology.
