I proposed nvRAM - CMOS SRAM backed by cell-for-cell flash.  Loads SRAM
from flash on power-up and stores into flash at power-down.  All that's
needed is a capacitor to extend the power-down cycle a bit.

Very fast, available in 8 to 32-bit wide architectures, up to 16Mbit per
package.

Claims to be guaranteed for 1M power cycles and doesn't require a battery.
