Abstract
An apparatus includes control circuits configured to connect to word lines that are coupled to NAND strings. The control circuits are configured to detect a defective word line, apply single word line erase voltages to the word lines to erase memory cells of the defective word line and, with the memory cells of the defective word line in an erased state, read data from neighboring memory cells of the NAND strings.
