Abstract

Disclosed are embodiments of structure including: a chip with an embedded magnetic random access memory (eMRAM) or other on-chip component susceptible to magnetic field-induced performance degradation; and magnetic shield(s) for protecting the chip. In some embodiments, a magnetic shield includes abutting magnetic layers having different magnetic properties. In other embodiments, a magnetic shield includes abutting magnetic layers (of the same or different magnetic materials) having offset patterns of openings (e.g., through-holes or mesh). In any case, the chip can be mounted on a board and contained in a package. Such magnetic shields can be located on the package (opposite the board) and/or on the board (opposite the chip) depending upon the expected location of a potentially adverse magnetic field.
