Description
Raja, Nehra, Dogra, and Rastogi built a simple two-terminal memristor, a resistor whose resistance remembers past voltage, from an amorphous calcium zirconate thin film sandwiched between gold and a conductive glass electrode. Such devices are candidates for dense memory and brain-like computing that conventional flash cannot scale to.
The device switched reliably and reproducibly at low operating voltages of about plus or minus 1 volt in their testing. It endured 1.2 times ten to the fifth switching cycles and held stored states for over 5.5 times ten to the third seconds without power. Uniformity held up both cycle to cycle and device to device across the fabricated samples examined. Spectroscopy supported a mechanism in which oxygen vacancies line up into conductive filaments that form and rupture with each switch, and the authors propose logic and data encryption uses.
