Novel RAM cell designs based on inherent capabilities of quantum-dot cellular automata

Content addressable memory cell in quantum-dot cellular automata

“…It also consumes two clocking cycles to transmit the input signal to the output. A QCA random access memory without set and reset ability has been suggested in [29]. This structure has a loop-based mechanism and is constructed based on SR-latch.…”

“…Coplanar wire crossing method has been employed in this structure. Another structure for RAM cell is presented in [29] with the same operation. This structure has been based on D-latch with an un-robust threeinput majority gate structure.…”

“…Many works such as [11,15,[26][27][28][29][30][31] focus on this problem. But these works have been done on RAM model, where the each memory location is accessed by a specific address.…”

Designing quantum-dot cellular automata counters with energy consumption analysis

“…Here denotes reduced Planck constant,   is the Coherence vector and   is the energy environment vector of the cell including its neighbors' effects which is obtained as: 11 1 2 , 0, ( ) ,…”

“…As a result, any optimization in its complexity and performance directly improves the performance of whole system. To date, lots of studies have been carried out by the researchers in designing efficient QCA memory cells, such as different structures for random access memory cell [10,11,15], well-optimized QCA architectures for flip-flops [13][14][15][16][17][18] and counter designs [12,13]. In addition, logical and arithmetical circuit designs have been extensively investigated in several studies [20][21][22][23][24]28,29].…”
