Abstract
A memory block recovery process is used to review and recover memory blocks of a memory device that have potentially been misidentified as bad blocks. The memory block recovery process is initiated when a threshold number of entries in a failed memory block list is exceeded. During the memory block recovery process, the failed memory block list is analyzed to determine whether there is any correlation between memory blocks that failed programming operations and memory blocks that were programmed prior to the memory block failing its programming operation. If there is a correlation, an independent program operation is performed on each memory block that failed its programming operation. If the independent programming operation on the memory block is successful, the memory block is reclaimed and the prior programmed memory block is identified as a bad block.
