4입력 다수결게이트를 사용한 QCA 기반 CAM 셀 설계

다국어 초록 (Multilingual Abstract)

In this paper, we propose a new content addressable memory (CAM) cell using Quantum-dot Cellular Automata (QCA), the next generation digital circuit design technology. CAM is a storage device that stores information, and it is a circuit that searches for information using information stored therein. CAM is an important circuit because it can provide fast execution speed in special tasks such as network switching. Existing QCA CAM cells are designed in a flat structure, so the required area of the circuit is large, and wiring is complicated because of using a 5-input voting gate to implement a 3-input AND gate used. The proposed circuit simplifies wiring connection using a new 4-input majority gate, and reduces the required area of the circuit by using a multi-layer structure. The operation of the proposed CAM cell is verified through simulation.
