New memristor better mimics synapses

At the device level, variability remains a significant issue for all memristor types. Scaling feature sizes down is likely to make variability worse. <a href="https:&#x2F;&#x2F;semiengineering.com&#x2F;integrating-memristors-for-neuromorphic-computing&#x2F;" rel="nofollow">https:&#x2F;&#x2F;semiengineering.com&#x2F;integrating-memristors-for-neuro...</a>

Was the transistor theoretically proposed similar to the memristor was? Wondering if people had as much hype for the transistor eventually appearing as we are about memristors.

So the memristor has been physically proven? I thought there was skepticism over whether it was even possible to make them.

What are the merits of memristors over solid state NAND and Intel optane technology?
