Abstract
An apparatus includes a memory and a memory controller. The memory includes a memory block that includes memory cells connected by word lines. The memory controller is configured to store data in the memory cells, and to identify a suspected short-circuit event in the memory block by recognizing a deviation of a performance characteristic of at least a given word line in the memory block relative to the performance characteristic of remaining word lines in the memory block.
