Logic and memory with nanocell circuits

Molecular electronics is an emerging field that seeks to build faster, cheaper, denser computers from nanoscale devices. The nanocell is a molecular electronics design wherein a random, self-assembled array of molecules and metallic nanoparticles is addressed by a relatively small number of input/output pins. The challenge then is to program the nanocell post-fabrication. We have previously demonstrated the ability to program individual simulated nanocells as logic gates. In this paper, we further explore the problem of programming nanocells and consider connecting nanocells into circuits using bistable latches at the interconnects. These latches are critical because they permit signal restoration. Simulated nanocell circuits for logic and memory are presented here.
