MSDRAM: Multivalued Sequence Storage of Random Access Memory Using DNA Technology

Abstract

The rapid growth in data generation demands innovative solutions for efficient storage and retrieval, far beyond the capabilities of traditional silicon-based Random Access Memory (RAM). DNA-based storage systems have emerged as a revolutionary approach, leveraging DNA's intrinsic properties such as high density, stability, and scalability. Unlike binary encoding, ternary RAM leverages the quaternary nature of DNA bases to represent multivalued data, thereby enhancing storage density and computational efficiency. This technology achieves unprecedented storage densities by mapping multivalued data to synthetic DNA sequences while implementing advanced biochemical techniques for storage. This paper introduces MSDRAM (Multivalued Sequence Storage of Random Access Memory), a novel architecture utilizing DNA technology to overcome the limitations of conventional storage systems. This proposed research sets the foundation for hybrid storage architectures, combining the strengths of molecular and silicon-based technologies to meet future computational demands. The proposed architecture of multivalued SDRAM demonstrates that it achieves a storage density of a single petabyte per gram of DNA, detailing its encoding unit, DNA-based storage medium, and access mechanisms that significantly outperform traditional RAM and binary-based DNA RAM in capacity and heat efficiency. This research highlights the potential of DNA technology for scalable, energy-efficient memory systems and addresses the challenges of heat, speed, and environmental sensitivity.
