Fingernail Sized Chip Could Potentially Store 1TB of Data

Engineers at North Carolina State University have created a material that could be used to create a chip capable of storing a terabyte of data. That's 250 million pages of text or 20 high-def DVDs.

To create this, they worked at the atomic level using a process called "selective doping" which is adding an impurity to a material, thereby changing its properties. In this case, they added nickel to magnesium oxide. This created clusters of nickel atoms no larger than 10 square nanometers, a 90% size reduction with what most other methods can get you.

This cannot only get us those 1TB chips the size of a fingernail, but also higher fuel economy for vehicles
and higher computer storage capacity.
