what is a protein memory?

Answer 1

Protein based storage is an experimental means of storing data. Using proteins that respond to light from bacteria found in salt water, a small cube can store large amounts of data. By using lasers the protein can be changed depending on various wave lengths, allowing them to store and recall data. As a result protein can be used to store enormous amounts of data using lasers to read and write binary code. With this new found technology scientists are now developing a larger more efficient storage media.
