In this letter, we proposed a novel operation of a share contact resistive random access memory (CRRAM) structure to realize a nonvolatile latch (NV latch) with a single transistor. With a share CRRAM structure and sequential input operations, the NV latch as well as and/ or functions have been successfully demonstrated. The new mixing approach of combining memory and logic in a single unit projects the possibility of new applications for VLSI circuits.
