Recently, there have been some significant advances in the fabrication and demonstration of individual molecular electronic switches and wires [1-5]. The objective of this brief presentation is to outline how one might design an ultra-dense electronic computer that incorporates such nanometer-scale molecular electronic devices. That is, based upon the advances to date, the speaker will describe what the molecular logic circuitry for such a nanoelectronic computer might "look" like? [6,7]. Some recent results will be discussed from the ongoing effort at The MITRE Corporation to develop a realizable architecture for a molecular-scale electronic computer.
