Abstract
Systems and methods are disclosed to detect and correct errors in a flash memory using an error correction cache that provides error correction information by accessing data from a physical block number (PBN) of the flash memory; and if a data error occurred, applying error correction information stored in the cache corresponding to the accessed PBN to correct the data error.
