I hadn't read about RRAM before, but from what Wikipedia has on it [1], it's been a technology of the shining press-release future for a while. E.g.: "In 2013, Crossbar introduced an ReRAM prototype as a chip about the size of a postage stamp that could store 1 TB of data. In August 2013, claimed that large-scale production of their ReRAM chips was scheduled for 2015. [...] Also in 2013, Hewlett-Packard demonstrated a memristor-based ReRAM wafer, and predicted that 100 TB SSDs based on the technology could be available in 2018 with 1.5 PB capacities available in 2020 [...]" [1] https://en.wikipedia.org/wiki/Resistive_random-access_memory https://en.wikipedia.org/wiki/Resistive_random-access_memory

True, but HP was looking at different applications. I’m not sure why they didn’t pan out - at the time it looked massively promising. Here they are playing with the analog aspect of it the same way we store multiple bits in flash cells, but doing math in their analog behaviour. Maybe the issue with using it for storage was long term stability, and this is not really an issue here.
