Abstract
An integrated circuit includes a magneto resistive RAM (MRAM) array having a plurality of MRAM cells, and a set of at least one Hall sensor circuit, each of the set including a Hall sensor to detect a magnetic field. The integrated circuit also includes magnetic processing circuitry for receiving at least one indication from the set of at least one Hall sensor circuit. The magnetic processing circuitry including an output to provide an indication of a possible magnetic field threat to the MRAM array based on the at least one indication from the set.
