DROM: Read Only Memory Storage in DNA Computing

Biomolecular programming performs computing utilizing many sorts of reactions and stores the information in biological macromolecules (proteins and nucleic acids). DNA (Deoxyribose Nucleic Acid) exhibits highly predictable molecular behavior, which assists in the construction of logical versions of operating systems and molecular computers. Read Only Memory (ROM), is a form of electronic storage that is built into a device during the manufacturing process. It might be a programmable general-purpose logic device, and a client can customize the storage device as a basic logic gate operation to complex mechanisms on a chip. In this proposed work, a ROM is designed using DNA-based gates. The attributes of DNA-based computing enable DNA-based ROM to execute billions of operations consecutively as well as provide immense storage in a compact space.
