A CBRAM-based Compact Interconnect Switch for Non-volatile Reconfigurable Logic Circuits

This paper presents a 2-to-2 interconnect switch based on Conductive Bridging Random Access Memories (CBRAMs), which can be used to form a switch box in reconfigurable logic circuits like FPGAs. Interconnect switching as well as configuration storage are achieved by the same resistive switching devices. The solution is stable without read disturb and false programming, and brings an area saving of more than two, compared to the current SRAM based circuits. It is a promising breakthrough for including permanent retention mechanisms in embedded systems at low cost.
