making big claims for sure. obviously idea/prototype and scalable system are very different things. geopolitical angle aside, this is one of the effort to replace current power dominated AI infrastructure approach. another one is optical computing, making even bigger advantage claims.
thoughts?

The technogrift of phase change memory strikes again! Surprised this isn't an IBM paper.
Similar research by IBM - any bets on when it makes it into real world use ?

I thought ReRAM and PCM were different things? Globalfoundries already sells eReRAM as a substitute to eFlash.
Planar Flash can't scale down anymore. I think it is mostly stuck at 40nm. Most foundries seem to be offering either ReRAM or MRAM as a replacement eNVM at thinner nodes.

The Nature paper focuses on ReRAM, just like the IBM one.
Our system uses high-performance RRAM chips that are fabricated in a foundry with a one-transistor-one-resistor (1T1R) cell structure in which each cell has eight conductance levels.
Well I think it is a good idea. There are several companies designing these hybrid intelligent memory AI accelerators. Not necessarily with ReRAM.
From what I understand the pioneers of ReRAM were HP with the memristor.
PCM is totally different because it used a process hard if not impossible to integrate with regular logic. It used chalcogenides.
