摘要： Techniques for providing non-volatile antifuse memory elements and other antifuse links are disclosed herein. In sonic embodiments, the antifuse memory elements are configured with non-planar topology such as FinFET topology. In some such embodiments, the fin topology can be manipulated and used to effectively promote lower breakdown voltage transistors, by creating enhanced-emission sites which are suitable for use in lower voltage non-volatile antifuse memory elements. In one example embodiment, a semiconductor antifuse device is provided that includes a non-planar diffusion area having a fin configured with a tapered portion, a dielectric isolation layer on the fin including the tapered portion, and a gate material on the dielectric isolation layer. The tapered portion of the fin may be formed, for instance, by oxidation, etching, and/or ablation, and in some cases includes a base region and a thinned region, and the thinned region is at least 50% thinner than the base region.

摘要： Techniques and circuitry are disclosed for implementing non-volatile storage that exploit bias temperature instability (BTI) effects of high-k/metal-gate n-type or p-type metal oxide semiconductor (NMOS or PMOS) transistors. A programmed bitcell of, for example, a memory or programmable logic circuit exhibits a threshold voltage shift resulting from an applied programming bias used to program bitcells. In some cases, applying a first programming bias causes the device to have a first state, and applying a second programming bias causes the device to have a second state that is different than the first state. Programmed bitcells can be erased by applying an opposite polarity stress, and re-programmed through multiple cycles. The bitcell configuration can be used in conjunction with column/row select circuitry and/or readout circuitry, in accordance with some embodiments.
