Methods, systems, and apparatuses are provided for operating a cache comprising dynamic storage having an array of cells. At a refresh interval, the array of cells of the cache is refreshed. A determination is made whether an error is found in the cache at the refresh interval. If no error is found in the cache, the refresh interval is repeatedly increased by a predetermined amount until an error is found. If an error is found, the error is recovered from. A determination is made if a number of line deletions for the cache is a maximum number of line deletions for the cache. If the maximum number of line deletions is not attained, a line having the error is deleted, and the number of line deletions for the cache is increased. If the maximum number of line deletions for the cache is attained, the refresh interval is decreased by the predetermined amount.
