Abstract
A method includes, in a memory block, which includes at least a string of memory cells that is selectable using at least a select transistor, sensing a current flowing through the string. A failure in the memory block, which causes the string to conduct even when unselected using the select transistor, is detected based on the sensed current. A corrective action is initiated in response to the identified failure.
