Systems and methods are provided for a scalable high-performance antifuse structure and process that has a low RC component, a uniform dielectric breakdown, and a very low, effective dielectric constant (keff) such that a programming pulse voltage is scalable with Vdd. One aspect of the present subject matter is an antifuse device that is positioned or coupled between a first metal level and a second metal level. One embodiment of the antifuse device includes a porous antifuse dielectric layer, and at least one injector Silicon-Rich-Insulator (SRI) layer in contact with the porous antifuse dielectric layer. In one embodiment, the porous antifuse dielectric layer includes SiO2 formed with air-filled voids. In one embodiment, the at least one injector SRI layer includes two injector Silicon-Rich-Nitride layers that sandwich the porous antifuse dielectric layer. Other aspects are provided herein.
