Abstract

See full text

An apparatus, according to one embodiment, includes a controller having a write driver, and a comparator circuit configured to detect a high resistance condition by comparing a first output voltage of the write driver with a second output voltage of the comparator circuit. A high resistance condition is detected in response to determining that the second output voltage of the comparator circuit is greater than the first output voltage of the write driver. Other systems, methods, and computer program products are described in additional embodiments.
