Abstract
A memory device includes a wordline zone table that stores information about how wordlines of one or more memory blocks are divided into wordline zones. The wordline zone table also stores a value associated with each wordline zone. When the memory device receives a command, a controller identifies a wordline associated with the command. The controller uses the wordline zone table to determine the wordline zone, and the value, associated with the wordline. The value is stored in a non-data wordline. When a find last good page (FLGP) process is initiated in response to an ungraceful device shutdown (UGDS) event, the controller determines the value stored in the non-data wordline. The controller compares the value in the non-data wordline to the values in the wordline zone table to determine which wordline zone matches the value. The FLPG process is applied to the wordline zone having the matching value.
