Memory in Motion : A Study of Storage Structures in QCA

Quantum Cellular Automata (QCA) is a new technology that replaces current flow as an information carrier by coulombic interactions of electrons within confined configurations. Prior work has investigated its potential as very dense logic. This paper uses a defining characteristic of such devices, namely pipelining that occurs even at the wire level, as the mechanism for memory structures that are formed recursively, rather than as conventional CMOS arrays, and hold the potential for extremely dense storage with embedded processing capabilities.
