Fingernail-size chip that holds 1TB of data

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.

"Instead of making a chip that stores 20 gigabytes, you have one that can handle one terabyte, or 50 times more data," Narayan said in a press release.
