Terabyte Nonvolatile Memory

IEEE Transactions on Electron Devices 54: 2762-2768

Results: Using silicon and copper, researchers have made a new type of ­memory that stores information by harnessing negative and positive charges to assemble and disassemble nanoscale metallic wires. Each ­memory cell consists of two electrodes separated by an electrolyte doped with copper ions. When a cell is in the off state, little current passes from one electrode to the other. When a "writing" voltage is applied, the ions line up and form a filament that bridges the electrodes, markedly increasing current. Reversing the voltage causes the filament to dissolve.
