1. A method, comprising:
determining whether a block of a memory device is an interior block within a memory structure comprised of a plurality of adjacent blocks;
generating parity data, corresponding to a plurality of word lines, coupled to each of the plurality of adjacent blocks of the memory device;
determining that a particular interior block needs additional parity data;
generating additional parity data for the particular interior block determined to need additional parity data; and
performing a data recovery operation based on the parity data, the additional parity data, or a combination thereof.
