Abstract: Counting status circuits are electrically coupled to corresponding status elements. The status elements selectably store a bit status of a bit line coupled to a memory array. The bit status can indicate one of at least pass and fail. The counting status circuits are electrically coupled to each other in a sequential order. Control logic causes processing of the counting status circuits in the sequential order to determine a total of the memory elements that store the bit status. The total number of memory elements that store the bit status indicate the number of error bits or non-error bits, which can help determine whether there are too many errors to be fixed by error correction codes.
