Engineers have created a new fingernail-size chip that can hold 1 trillion bytes (a terabyte) of data -- 50 times the capacity of today's best silicon-based chip technologies.
The engineers, from North Carolina State University, said their nanostructured Ni-MgO system can store up to 20 high-definition DVDs or 250 million pages of text, "far exceeding the storage capacities of today's computer memory systems."
The team of engineers was led by Jagdish "Jay" Narayan, director of the National Science Foundation Center for Advanced Materials and Smart Structures at the university.
The engineers made their breakthrough using the process of selective doping, in which an impurity is added to a material whose properties consequently change.
