AbstractIntegrated circuits in NASA spacecraft and vehicle electronics must operate over large temperature extremes and mitigate radiation effects that can result in upset and/or destruction of devices. PrivaTran has previously demonstrated a two-terminal, electronically-programmable resistor as a nonvolatile memory (NVM) element with performance metrics exceeding those of competing technologies, and herein proposes this device as a radiation hardened NVM array formed within the metal interconnect layers of the integrated circuit and fully integrated in a 3D architecture, resulting in significant savings in weight, power and reliability.
