Modeling and Simulation of DNA Origami based Electronic Read-only Memory

Deoxyribonucleic acid (DNA) has emerged as a promising building block for designing next-generation ultra-high density storage devices. Although DNA is highly durable and extremely high density in nature, its potential as the basis of storage devices is currently hindered by limitations such as expensive and complex fabrication processes and time-consuming read-write operations. In this article, we propose the use of a DNA crossbar array architecture for an electrically-readable Read-Only Memory (DNA-ROM). For DNA-ROM, we have chosen two DNA strands for representing Bit 1 and Bit 0 respectively. DNA charge transport has been studied through a ‘contact-DNA-contact’ setup. The results obtained from the DNA charge transport study have been used to analyze the crossbar array. The performance has been analyzed by loading an image onto a 128×128 crossbar. For this application, we have observed a bit error rate of 4.52% and power consumption of 6.75 µW.
