Abstract: In one aspect, an integrated circuit includes a first conductive layer and a magnetoresistance element (MRE) disposed over and coupled to the first layer through first vias. The MRE is magnetized to produce a first magnetic orientation. The first layer is disposed over and coupled to a second conductive layer in the circuit through second vias. The circuit also includes a metal filler disposed proximate to the MRE. The metal filler is positioned over and coupled to the second layer through third vias. The circuit also includes a thermal dissipation path resulting from a physical input applied to the first MRE. The thermal dissipation path extends through the first through third vias, the first and second layers, an integrated circuit interconnection, and the metal filler.

Abstract: A method comprising: performing a first read from an address in a data storage module by using a first read voltage; storing, in a first register, data that is retrieved from the data storage module as a result of the first read; performing a second read from the address by using a second read voltage; storing, in a second register, data that is retrieved from the data storage module as a result of the second read; detecting whether a weak bit condition is present at the address based on the data that is stored in the first register and the data that is stored in the second register; and correcting the weak bit condition, when the weak bit condition is present at the address.

Abstract: Systems and methods described herein are directed towards integrating a shield layer into a current sensor to shield a magnetic field sensing element and associated circuitry in the current sensor from electrical, voltage, or electrical transient noise. In an embodiment, a shield layer may be disposed along at least one surface of a die supporting a magnetic field sensing element. The shield layer may be disposed in various arrangements to shunt noise caused by a parasitic coupling between the magnetic field sensing element and the current carrying conductor away from the magnetic field sensing element.
