Abstract :
A NOR Flash memory fully functional at 1 V is demonstrated, based on an inductor built directly into the package. A ferromagnetic nucleus is wound by means of the bonding wires and the first package substrate metal layer. The magnetic field does not affect the system since it is strictly confined into the toroidal nucleus. The whole system is enclosed into a standard BGA package 8times14times1.4 mm with 88 balls
