Non-volatile memory (NVM) technology highly resistant to ionizing dose and radiation effects in general continues to be a challenge for space missions. Novel NVM nano-ionic technologies known as conductive bridging random access memory (CBRAM), a resistive circuit technology, exhibits great promise for both high density memory and high total ionizing dose resilience. In this work, it is discovered that CBRAM can be sensitive to high TID levels. However, this novel technology can be radiation-hardened by process, which is demonstrated in this paper.
