ABSTRACT:
If a memory block in a flash memory device is found to have a defect, a memory block quality indication is generated in response to the type of memory defect. This indication is stored in the memory device. In one embodiment, the quality indication is stored in a predetermined location of the defective memory block. Using the quality indication, it can be determined if a system's error correction code scheme is capable of correcting data errors resulting from the defect.
