Abstract
A storage device is disclosed herein. The storage device comprises a block including a plurality of memory cells and a circuit coupled to the plurality of memory cells of the block. The circuit is configured to program memory cells of a plurality of strings of a word line of the block and verify, for a plurality of sets of the memory cells, a data state of a set of the memory cells, where each set of the plurality of sets of the memory cells includes a memory cell from each string of the plurality of strings of the word line. Further, the circuit is configured to determine a number of sets of the plurality of memory cell sets that are verified to be in a first data state and determine, based on the number of sets, whether the block is faulty.
