HSR too close to cliff

That HSR definition looks too close to the cliff!

I had thought Crossbar utilized transistor-less "crossbar" arrays. Adding the transistor only worsens the density, compared to without.

Ah, I see the I-V indicates no self-compliance. That makes it transistor-bound. It's a waste of the built-in HSR.

Their selector is or closely resembles the threshold switching device like the ovonic type.

to resistion - I am not sure about that. Looks like current still increases as voltage increases after the programming. And the device seems to be programmed w/o external current compliance, which is good.

to resistion -  it seems that they are using a passive crosspoint structure ("transistor-less" crossbar array) considering the core memory circuit pic shown above.

I guess they are refering to mux/demux transistors outside of the passive crosspoint memory structure (a circuit designer's point of view).

The sign of applied compliance is the abrupt current jump in SET discontinuous with dI/dV afterward

Well, I have to admit that I have a great big Cheshire Cat-type grin plastered on my face at the moment, because the prototype for my Vetinari Clock project is now well underway.
