Abstract
Mechanisms are provided, in a Not AND (NAND) flash memory device, for providing hybrid error correction management. A NAND flash memory module and a node controller coupled to the NAND flash memory module are provided along with a hardware logic implemented error correction code (ECC) engine associated with the node controller. The node controller is configured to determine whether an error count is less than or equal to a first threshold number of error bits and, in response to the error count being less than or equal to the first threshold number of error bits, performing correction of the error bits by the hardware logic implemented ECC engine associated with the node controller. The node controller is also configured to forward uncorrected data to a software logic implemented ECC engine, in response to the error count being greater than the first threshold number of error bits.
