Abstract

Dynamic storages are subject to intermittent bit failures which can become uncorrectable by the error correcting circuitry (ECC) if a cleanup operation is not periodically performed. Normally, the cleanup operation is a separate operation, and if done through programming, there is performance degradation. Dynamic storages also require periodic refresh. Normally, during refresh the data is not read out and applied to the error correcting circuitry. The present arrangement provides the ability to do error correction and a store operation during refresh.
