I saw this new type of memory from Microchip Serial EERAM which looks pretty cool.
Yon can read/write to it using I2C as you normally would...but without limits...if the chip loses power, it quickly writes the contents of its ram to EEPROM (rated for 1M writes) before shutting down...and automatically recalls that data from EEPROM to RAM on power-up...
I can't think of a project where I'd need this...but it's nice to know the tech is out there for more frequent memory writes...at $0.80 a pop, it's cheaper than FRAM if you have an application that requires frequent writes that need to be saved.
