Researchers in Japan come with some research for using a new proteins as storage device. It means there's a way to replace conventional magnetic and optical storage systems, which are quickly approaching their memory storage capacities.

As we know that proteins are the main source of our storage system in the brain. Scientist has come long way to exploring the possibility to use proteins and others biological materials to build memory based devices, that has a potential capabilities to  processing faster and have a greater storage capacity than current existing materials. One of the challenge is use some known proteins for practical use.

Tetsuro Majima and colleagues used a special fluorescent protein to etch or "record" a specific information pattern on a glass slide. Using a novel combination of light and chemicals, the researchers demonstrated that they could "read" the pattern and subsequently erase it at will.
