An anonymous reader writes "A single-atom DRAM which was demonstrated with a slo-mo movie of the atomic process of setting and erasing a bit on a single atom, getting IBM on the next Science. Videos of atomic processes inside chips was not possible until now, leading to IBM's claim that its pulsed-STM (that makes the moview) will lead to a new atomic-scale semiconductor industry, and not just for memory chips, according to this EETimes story:
"The ultimate memory chips of the future will encode bits on individual atoms, a capability recently demonstrated for iron atoms by IBM's Almaden Research Center in San Jose, Calif., which unveiled a new pulsed technique for scanning tunneling microscopes (STMs). Pulsed-STMs yield nanosecond time-resolution, a requirement for designing the atomic-scale memory chips, solar panels and quantum computers of the future, but also for making super efficient organic solar cells by controlling photovoltaic reactions on the atomic level."
The original STM is what enabled chip makers to perfect the current DRAM and flash memories, so it makes sense that turning the STM into a high-speed movie camera to record individual atoms could result in atomic memories, better solar cells and the ultimate goal--atomic scale quantum computers."
