The lower pulse usually takes an exponentially longer time.

Seems the oxygen should prefer continuing upward into the Hf or Ta rather than return to the filament, which would still have higher oxygen concentration than a metal.

Resistion: If it was down to me I would just repeat the step down pulse train and that would give the adavantage of the step down pulse effect and be the equivalent of repeating the maximum pulse. There is a contact email address on the VLSI paper who may be able to provide a more accurate answer. It is yylin@fudan.edu.cn

The complementary atomic switch looks like two CBRAM cells with a common upper electrode. Any two cells connected the same bit line would behave the same way.

The Shanghai group is not being entirely straightforward about monitoring current during the SET down ramp. What happens when the ramp reaches 0 without success? Why not stay at the highest level all the way?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
