Non-volatile memory for low power designs

9 Jun 2015

I came across a mention in a newsletter recently of the Texas Instruments line of FRAM based MSP430 microcontrollers and thought a short post on FRAM would be of interest.

 

If you aren’t familiar with FRAM (also called FeRAM), think of it as essentially a non-volatile SRAM. FRAM was commercially developed primarily by Ramtron International starting in the mid 1980s.

    OMG do I remember those days. Even using switches to see loops in code on 370/168 on batch machine of course. TSO was too online back then LOL.

    I think of FRAM as tiny, cheap magnetic-core memory image  When I got started with mini-computers, they had core memory so if you turned the power off whatever was in memory was still there when you turned the power back on.  That was very convenient when the only way to load programs was through front panel switches or paper tape. image

    It is interesting. When I first heard of FRAM it was being touted for practically limitless write cycles compared to EEPROM and Flash and the low-power aspect was an added bonus. At the time it struck me as another technology solution looking for a problem. Now it seems the low-power aspect is FRAM's main advantage over EEPROM and Flash and the trillions of write cycles is the added bonus.

    I find that very interesting trend of technology changes. Thanks for the heads up.
