Abstract
In some situations, a leak on a wordline may be a localized problem that causes data loss in a block that contains the wordline. In other situations, such as when the leak occurs near a peripheral wordline routing area, the leak can affect the entire memory die. The storage system provided herein has a fatal wordline leak detector that determines the type of leak and, accordingly, whether just the block should be retired or whether related blocks should be retired.
