Abstract
A tamper-resistant packaging approach protects non-volatile memory. According to an example embodiment of the present invention, an array of magnetic memory elements (-) in an integrated circuit () are protected from magnetic flux() by a package () including a magnet (). Flux from the magnet is directed away from the magnetic memory elements by the package. When tampered with, such as by removal of a portion of the package for accessing the magnetic memory elements, the package allows the flux to reach some or all of the magnetic memory elements, which causes a change in a logic state thereof. With this approach, the magnetic memory elements are protected from tampering.
