Fully BEOL-Compatible Switch Boxes Using RRAMs and Thin Film Transistors for Reconfigurable and Secure ICs

In this paper, we report Resistive Random Access Memory (RRAM) and Thin Film Transistors (TFT) based Switchboxes (SB) for Integrated Circuits (IC) design obfuscation and secure manufacturing. Our work shows that RRAM-TFT provide promising route for implementing SBs without compromising area in CMOS front end. Finally, we demonstrate its application for design obfuscation and reconfiguration of asynchronous logic cells.
