i seem to remember HP having made these a number of years ago

But what they watered it down to (and not delivered on that either) seems to be roughly equivalent to that fancy flash memory you can buy now for the new intel chipsets.

  It's unclear to me if the problem was a lack of vision on the part of HP or if the technology they came up with has fundamental problems that prevent it from being practical. Either one seems plausible.

    Don't know either. But if you google for something like - memristor oxygen transfer problem - lots of stuff comes up.

HP's lab (Stanley Williams) made their memristor announcement 10 years ago. "The missing memristor found" https://www.nature.com/articles/nature06932 https://www.nature.com/articles/nature06932 and still working on it "Capacitive neural network with neuro-transistors" https://www.nature.com/articles/s41467-018-05677-5 https://www.nature.com/articles/s41467-018-05677-5

This article from Ars Technica talks a little bit about memristors and HP's plans for "The Machine". The original plan was for The Machine to demonstrate this technology, but HP ended up removing feature after feature (including memristor technology) before it's release. They quote John Sontag from HP in the article: "The simplest way to think about it is this—take a DRAM DIMM out, and put a memristor DIMM in,” said Sontag. “You now have another pool of memory that’s denser and nonvolatile. It’s a new class of memory—the consequence for operating systems is that moving stuff around from I/O devices [to and from disk] becomes unnecessary." https://arstechnica.com/information-technology/2014/06/hp-labs-machine-dissolves-the-difference-between-disk-and-memory/ https://arstechnica.com/information-technology/2014/06/hp-la...

  Doesn't magnetic core memory (which has been around forever) do similar things?

    The density is terrible and the read process is destructive.

      Both seem to apply equally well for memristors. In both theory and practice.
