FRAM seems like the wrong technology for a looper. In particular, FRAM wears out on both reads and writes.

I'd expect SRAM to be best, as most "loopers" for musicians are only active while the device is on (ie, non-persistent), with Flash to be 2nd best (you lose out on write-durability, but rereading durability is infinite unlike FRAM).

EDIT: https://www.fujitsu.com/uk/Images/MB85RS4MT.pdf

So that's 10^13, or 10-trillion writes (which includes reads for FRAM). So if its read 10 times per second, that's 1-trillion seconds or I guess 30,000+ years of use. Hmmm... maybe that's enough durability then. Lol. I guess that's fine.
