Abstract:
An apparatus includes a non-volatile memory and a controller. The controller is operatively coupled to the non-volatile memory and configured to perform read and write operations on the non-volatile memory using codewords as a unit of read access. The controller includes an error correction engine configured to perform an error correction on codewords read from the non-volatile memory, and, if the error correction fails, to perform one or more retry procedures. The controller is further configured to perform one or more background procedures as a result of the error correction or one or more of the retry procedures not being successful and send an error message as a result of all of the retry procedures not being successful. The one or more background procedures are directed to determining a cause of the error correction failure.
