ABSTRACT:
A one-time non-conductive programmable element which is programmable to conduct current is provided. The programmable element comprises several anti-fuses connected in parallel with each other. According to one embodiment of the present invention, each anti-fuse of the programmable element includes first and second conductive plates and a dielectric layer between the two conductive plates. The first conductive plates of all anti-fuses are connected to each other and the second conductive plates of the anti-fuses are connected to each other to form the programmable element of the present invention. The programmable element provides a larger total surface area of the dielectric layer through several anti-fuses that are connected in parallel with each other. During programming, the larger surface area substantially improves the likelihood of capturing a higher defect area of the dielectric layer than was previously possible and allows the formation of strong electrical contact between the two plates having a programmed state resistance that can be controlled with relative accuracy.
