Atom Switch with Improved Cycle Endurance using Field Enhancement for Nonvolatile SoC

Multi-usage atom switch as "nonvolatile routing switch in FPGA" and "nonvolatile memory (NVM)" is newly developed for ultra-low power SoC in IoT applications. A novel Cu electrode structure inducing an electric field enhancement achieves 100k-cycle endurance and 10-year retention for NVM. The developed atom switch enables both a nonvolatile FPGA macro and an NVM macro to be embedded in a single SoC.
