1. A chip package including: an MRAM chip including a set of chip contact pads formed substantially flush with a first surface of the MRAM chip; a set of package contact pads disposed on an exterior surface of the package; a set of bonding wires electrically connecting the chip contact pads to the package contact pads; a first soft-magnetic shield disposed inside the package adjacent to the first surface of the MRAM chip, a surface of the first shield confronting the MRAM chip being larger than the first surface of the MRAM chip and extending beyond the MRAM chip on opposing sides, the first shield having at least one via with at least one bonding wire passing through the via; and a second soft-magnetic shield disposed adjacent to a second surface of the MRAM chip opposite to the first surface of the MRAM chip, the second soft-magnetic shield having an edge that extends toward and contacts the first shield, thereby encapsulating the MRAM chip.
