Abstract
Devices and methods are provided in which a magnetic sensitive semiconductor chip, such as a magnetoresistive random-access memory (MRAM) chip, is shielded from magnetic interference by a magnetic shielding layer. A device includes a housing that defines an exterior surface. A semiconductor chip is disposed within the housing, and the semiconductor chip is spaced apart from the exterior surface of the housing. A magnetic shielding layer is spaced apart from the semiconductor chip by a distance less than 5 mm.
