The usual way to cram more storage capacity into memory chips is to shrink the bits that hold the 1s and 0s of computer information. Researchers from the University of Southern California and NASA have built a prototype molecular memory device that puts more memory into one place by storing three bits in the same spot.

A memory chip based on the researchers' prototype would be able to hold 40 gigabits -- about a DVD's-worth of data -- per square centimeter, and the method has the potential to produce memory that holds 10 times that. Today's flash memory chips hold about 1 gigabit per square centimeter.
