Abstract: Methods of operating apparatus include receiving user data for programming to a grouping of memory cells of the apparatus, associating an address of the grouping of memory cells with the user data, determining whether power loss to the apparatus is indicated while programming the user data to the grouping of memory cells, and if power loss to the apparatus is indicated while programming the user data to the grouping of memory cells, programming the address of the grouping of memory cells to a different grouping of memory cells of the apparatus. Methods of operating apparatus further include checking whether power loss to the apparatus during programming of user data to a grouping of memory cells of the apparatus is indicated, and, when power loss is indicated, checking feature settings of the apparatus to determine a location of the apparatus containing an address of the grouping of memory cells, and recovering the address of the grouping of memory cells from the determined location.
