Abstract
A storage system caches, in volatile memory, data read from non-volatile memory. After detecting an uncorrectable error in the data cached in the volatile memory, the storage system replaces the cached data with data re-read from the non-volatile memory and updated to reflect any changes made to the data after it was stored in the non-volatile memory. The storage system can also analyze a pattern in data adjacent to the uncorrectable error and predict corrected data based on the pattern.
