Abstract
A system and method for providing and programming a programmable inductor is provided. The structure of the programmable inductor includes multiple turns, with programmable interconnects incorporated at various points around the turns to provide a desired isolation of the turns during programming. In an embodiment the programming may be controlled using the size of the vias, the number of vias, or the shapes of the interconnects.

8. An inductor comprising:
-
a first interconnect connected to a first turn of conductive material through a first via and connected to a second turn of conductive material through a second via, wherein the first interconnect, the first via, and the second via form a first fuse with a first resistance; a second interconnect connected to the second turn of conductive material through a third via and connected to a third turn of conductive material through a fourth via, wherein the second interconnect, the third via, and the fourth via form a second fuse with a second resistance greater than the first resistance; and a third interconnect connected to the third turn through a fifth via and connected to the second turn through a sixth via, wherein the third interconnect, the fifth via, and the sixth via form a third fuse with a third resistance greater than the second resistance. - View Dependent Claims (9, 10, 11, 12, 13)
