Arrays of 7-nanometer magnetic nickel nanodots, assembled by researchers at the National Science Foundation's Center for Advanced Materials and Smart Structures (CAMSS), aim at a 500x increase in memory density, to 10 trillion bits per square inch.
At such densities, coin-sized chips holding 5 terabits each could pack the entire Library of Congress into "a pocket full of change," said Jagdish Narayan, professor of materials science and engineering at North Carolina State University and CAMSS director at the university. Narayan performed the work with research associate Ashutosh Tiwari.
