This paper presents a novel memory architecture for implementation by quantum-dot cellular automata (QCA). The proposed architecture combines the advantages of reduced area of a serial memory with the reduced latency in the read operation of a parallel memory. An extensive evaluation with respect to latency and area is pursued. For area analysis, a novel characterization which considers cells in the logic circuitry, interconnect as well as the unused portion of the Cartesian place as QCA layout, is proposed.
