Abstract:
Systems and methods are disclosed for data recovery using outer codewords stored in volatile memory. Outer codewords can be associated with one or more horizontal portions or vertical portions of a non-volatile memory (“NVM”). In some embodiments, an NVM interface of an electronic device can program user data to a super block of the NVM. The NVM interface can then determine if a program disturb has occurred in the super block. In response to detecting that a program disturb has occurred in the super block, the NVM interface can perform garbage collection on the super block. The NVM interface can then use outer codewords associated with the super block to recover from any uncorrectable error correction code errors detected in the super block.
