Background/Objectives: Quantum-dot Cellular Automata (QCA) is a new nanoscale technology that is expected to be a persuasive replacement of CMOS technology. QCA technology competing for features concerning low power consumption, small physical size, and ultra-high speed. These features are beneficial for memory design. This study presents a new structure of the CAM cell in QCA technology. The presented cell is carried out in an optimal form by using a proposed unique block. Method: In this study, the QCADesigner tool was used for circuit design and the QCAPro tool was used for power analysis. Both of these tools were used in default parameters. Findings: It was found that the proposed CAM cell is less complexity and efficient in power consumption with improvements by 6%, 29% and 15% in terms of leakage, switching and total energy consumption. Improvement: The CAM cell is the main building block for the whole memory. So, the reduction in complexity and power consumption in the CAM cells is important to reach an optimal memory circuit.
