Latest Patents
One of Voegli's latest patents focuses on high-efficiency miniature magnetic integrated circuit structures. This invention provides a magnetic memory element that is single domain in nature and features a geometry designed to mitigate the effects of half-select noise. The magnetic memory element can take the form of a magnetic post or tube, with an aspect ratio ranging from 2:1 to 4:1. The outside diameter of the magnetic tube or post is ideally less than 0.8 microns, and preferably 0.6 microns or less. This design allows the magnetic post or tube to function as a single magnetic domain. The skin of the tube is made from a magnetic material, while the interior consists of a non-magnetic material such as copper, gold, or silicon. The coercivity of the magnetic tube structure can be adjusted by varying the thickness of the magnetic skin, making it scalable to smaller geometries as lithographic techniques improve. The combination of a very small, single-domain size and a relatively large aspect ratio results in uniquely desirable properties. Current levels within reasonable expectations operate to switch the state of the magnetic tube only when it is destabilized by running current through it. When current flows through the magnetic tube, its state can be changed by running modest currents in opposite directions through two parallel conductors on either side of the tube. This switching mechanism produces a signal that is typically 10-15 times stronger than those generated by conventional magnetic memory elements. The magnetic tube also functions as a vertical magnetic field generator and can be positioned in close proximity to a magnetic field sensor, such as above the gate of a magFET.
