Nanotechnology Helps Increasing Rate of Digital Data Processing, Storage
Tehran, Iran | Posted on March 9th, 2015Small but quick memory cells can be designed by using the results of the research for the production of computers, mobile phones and smart TVs.
Quantum Cellular Automata (QCA) is one of the emerging technologies at nanometric scale for the production of future digital circuits. This technology has attracted the attention of many researchers in recent years due to the three characteristics of high density, high speed and low power consumption.
The executor of the plan, Shahin Angizi, explained that memory element is one of the important circuits in all nano-electronic devices, and added, "There are some challenges in the implementation of this element for data storage in quantum cellular automata. In this research, unique properties of quantum cellular automata technology have been used to increase the rate of data storage and data recovery processes in digital systems. In the end, a novel structure has been designed for a single-bit memory cell."
The main result of the research is the presentation of the fastest yet smallest memory cell in nano-electronic devices. The majority of digital systems, including computers, mobile phones and smart TVs use memory cells for data storage and data recovery.
In addition, a high-efficient design has been made on a five-input-majority gate in a way that all QCA circuits can use it.
The proposed memory cell has been designed at a dimension of 0.08 micrometers by using 88 quantum cells, and its correct performance has been proved. Moreover, significant improvement was attained in the rate of data processing in comparison with the previous studies.
Results of the research have been published in Microelectronics Journal, vol. 46, issue 1, 2015, pp. 43-51.
