I have a little envelope of cores that I’ve been meaning to do something with for years, but they are just so tiny I haven’t wanted to mess with them. (Not sure when they were made, but I’m assuming fairly late based on the size.)
Dataram, back in the day, made 'generic' core memory planes. That is, the had a relatively speaking simple electrical interface, and many vendors just implemented whatever was needed to hook it up to the vendors (usually) proprietary interface.
I have a couple I've been (very) slowly trying to get working with a modern-ish microcontroller with USB connectivity.
You can buy FRAM (Ferroelectric RAM) which are effectively the same thing just in smaller package. But I have seen them only about few kB. However the amount of R/W operations is effectively unlimited,
Yes, although (like some flash technology) read cycles are slower than write cycles, and it takes longer to read a 0 bit and than 1 bit (or vice versa).
It is the future, and has been the future for almost 40 years already! I bet that's what the hoverboards will use inside their microcontrollers — gotta drive those portable fusion reactors reliably!

I doubt that this is the future. The future is to do calculations directly in the RAM.
You don't say.

You can get them up to 16Mb/2MB. Which is 1/128 what NOR flash comes in for a similar price and package. Certainly a trade.
I think MRAM is the future though.

I though bubble memory was the future. Dammit, I missed another memo.
With the current DRAM shortages, this couldn't have come at a better time.
I thought they meant bus width ...still impressed for entirely unexpected reasons.
