Abstract
An apparatus includes control circuits that are configured to connect to a plurality of nonvolatile memory cells. The control circuits are configured to determine that a first portion of user data from the plurality of memory cells that was found to be uncorrectable by ECC is unrecoverable by a first Exclusive OR (XOR) operation using first XOR data and a second portion of user data. The control circuits are further configured to, in response to the determination, recover the first portion of user data by a second XOR operation using second XOR data and a third portion of user data.
