I'm not sure if this is the same technology, but regardless it's also cool: https://www.adafruit.com/product/1897

Not quite - the chip the article refers to is the 47L04 [0], which is "just" NVSRAM built out of a RAM + EEPROM. I do agree on FeRAM being cool, though - I have a few I2C chips en route, and I can't wait to get my hands on them.

		You could also consider MRAM. Which is available in larger sizes - up to 4 Mbit on SPI bus in the MR20H40, and 128 Mbit in EM128LXQ (but it gets unreasonably expensive when this big). https://www.everspin.com/family/mr20h40?npath=259

		Thanks to both of you for bringing FRAM onto my radar!
