Quantum-dot Cellular Automata (QCA) is a new emerging nano-electronic
technology. Owing to its many favorable features, such as low energy
requirements, high speed, and small size, QCA is being actively suggested as
a future CMOS replacement by researchers. Many digital circuits have been
introduced in QCA technology, most of them aiming to reach the function with
optimum construction in terms of area, cell count and power consumption. The
memory circuit is the main building block in the digital system therefore the
researchers paid attention to design the memory cells with minimum
requirements. In this paper, a new methodology is introduced to design two
forms of CAM cells. The proposed designs required two 2:1 multiplexers, one
OR gate and one inverter. The first proposed design reduces the power
consumption by 53.3%, 35% and 25.9% at (0.5 Ek, 1 Ek, and 1.5 Ek) while
the second design by 53.2%, 31.9% and 20.5% (0.5 Ek, 1 Ek, and 1.5 Ek)
respectively.
