Methods, apparatus, systems, and data structures may operate to combine block management data with a portion of data, to generate error correction data for the combined portion, and to store the data, the block management data, the error correction data for the combined portion, and error correction data for the data in a memory. Methods, apparatus, systems, and data structures may operate to generate or store error correction data for each of a plurality of sectors of a page except for a particular sector in the page and combine block management data with the particular sector to generate a modified sector. Additionally, various methods, apparatus, systems, and data structures may operate to generate or store error correction data for the modified sector and combine the plurality of sectors, the error correction data for each of the plurality of sectors other than the particular page, and the block management data and the error correction data for the modified sector.
