You could also make use of some of those rather quite interesting MRAM
memory chip technology that's about. All the non-volatility of core,
with all the speed, low-profile, and low power consumption of modern
volatile RAM technologies.

Unfortunately, the cost of MRAM chips is rather a lot, especially
since you can't just order small batches. Minimum order on Mouser was
128 chips at something like $20 CAD per.
