    Abstract: Some implementations provide a die that includes a magnetoresistive random access memory (MRAM) cell array that includes several MRAM cells. The die also includes a first ferromagnetic layer positioned above the MRAM cell array, a second ferromagnetic layer positioned below the MRAM cell array, and several vias positioned around at least one MRAM cell. The via comprising a ferromagnetic material. In some implementations, the first ferromagnetic layer, the second ferromagnetic layer and the several vias define a magnetic shield for the MRAM cell array. The MRAM cell may include a magnetic tunnel junction (MTJ). In some implementations, the several vias traverse at least a metal layer and a dielectric layer of the die. In some implementations, the vias are through substrate vias. In some implementations, the ferromagnetic material has high permeability and high B saturation.

    Abstract: Thermal conductivity in a stacked IC device can be improved by constructing one or more active temperature control devices within the stacked IC device. In one embodiment, the control devices are thermal electric (TE) devices, such as Peltier devices. The TE devices can then be selectively controlled to remove or add heat, as necessary, to maintain the stacked IC device within a defined temperature range. The active temperature control elements can be P-N junctions created in the stacked IC device and can serve to move the heat laterally and/or vertically, as desired.
