Abstract
A system and method is disclosed for detecting and correcting for errors in mapping table information stored in volatile memory of a non-volatile memory system. The method may include checking for mapping entry errors when retrieving mapping data for the non-volatile memory from a volatile memory cache. When an error is discovered, the method includes the processor generating a set of candidate mapping entries each having a different single bit difference from the mapping entry discovered to have an error. Each candidate is tested against one or more mapping data accuracy tests and, when one of the candidates is found to be a correct mapping entry based on the one or more tests, the original mapping table entry with the determined defect is replaced with the successful candidate mapping entry.
