-a This involves weird characteristics of hafnium oxide
-a films - and more carefully shaped electrodes. Seems
-a the bad problems get BETTER when you make everything
-a smaller (ok, a few extra tweaks are needed).

-a I've used ferroelectric memory in solar-powered field
-a projects in the past. It's fast, no wait states need
-a be used for reading/writing. It doesn't need tons of
-a power. It also has superior data retention and cycle-
-a endurance. In theory it's a great technology.

-a The prob, at least back around 2010 and STILL, is
-a the density. 256mb seems to be the usual limit for
-a commercial devices, I think I've seen a 512mb chip
-a on DigiKey.

-a The small capacity was fine for what I was using it for,
-a storing params so the device could shut down and start
-a up again with all variables exactly the same. These were
-a microcontrollers, the FEMs were more than good enough.

-a NOW ... flash uses a LOT of electricity to operate,
-a and is still relatively slow and has a kinda limited
-a lifespan. Various NVM ram techs are out there, but
-a are harder to deal with than flash or FE.

-a Now IF this article lives up to its hype, high density
-a ferroelectric may finally be in reach. This will save
-a battery power on portable devices, maybe even in some
-a data centers.

-a Check DigiKey and Mouser ... ferro-electrics are still
-a sold. Most are I2C but there are are other popular
-a variants. Interfacing with microcontrollers is quite
-a easy, compared to DRAM/SRAM and such. I'd still rec
-a them for devices where power consumption is a critical
-a part of the equation.

-a Sorry, the PIs are power hogs for various reasons ...
-a think Arduino or other microcontrollers instead. THEN
-a you'll see the advantage.

Fast enough to replace DRAM, non-volative across power-off ... almost
reminds me of old-time ferrite core memory!
