For example, a word line may have an electrical short between a structure of the word line and another structure in a non-volatile memory array. In another example, the memory cells of a word line may be worn to the point that the word line can no longer be reliably used to store and read data. Said another way, a bad word line may have too many errors to be useable, or may have been retired from further use, or may have failed. Alternatively, or in addition, memory cells of a word line may have such poor performance that the word line can no longer be used and still need operating performance requirements or expectations.Bad word lines may be designated as such when a non-volatile memory array is manufactured and/or as word lines become bad word lines as the word lines are used.
