Abstract
Method includes identifying, while programming sets of pages to dice of memory device, multiple sets of pages experiencing a variation in temporal voltage shift satisfying a threshold criterion; partitioning a set of pages of the multiple sets of pages into a set of fixed-length partitions; storing, in a metadata table, a value to indicate a size of each fixed-length partition; receiving a read operation directed at a page of the set of pages; determining, based on a logical block address of the read operation and on the value that indicates the size of each fixed-length partition, a partition of the set of fixed-length partitions to which the read operation corresponds; and searching within the metadata table to determine a block family to which the partition is assigned, wherein the searching is based on a first value associated with the set of pages and a second value associated with the partition.
