If you're curious like I was, it appears that MRAM is susceptible to higher than usual magnetic fields, but shielded to prevent interference up to a certain tolerance. "Everspin MRAM products are designed to be highly immune to magnetic fields normally found in commercial, industrial or AEC-Q100 Grade 1 applications. However, if there is concern that an MRAM device is expected to be in close proximity to a magnetic field, it may be prudent for the designer to verify that a magnetic field does not exceed the magnetic immunity specifications of the MRAM."
