"The new device is built from arrays of resistive random-access memory (RRAM) cells.... The team was able to combine the speed of analog computation with the accuracy normally associated with digital processing. Crucially, the chip was manufactured using a commercial production process, meaning it could potentially be mass-produced."

This is an analog pc: https://en.wikipedia.org/wiki/Analog_computer

https://en.wikipedia.org/wiki/Vacuum-tube_computer

It does seem to be talking about this, analog doesn't from my understanding use 1 or 0 as a representation. It is true that the cpu uses voltage as you stated, but what differentiates it from analog is that in analog the volatge isn't represented as 0 or 1 and is used as is in calculations.

They are not programmed, they are physically made to preform the calculation from my understanding, like for example the https://en.wikipedia.org/wiki/Antikythera_mechanism
