The FRAMs are getting cheaper- ie. Fujitsu's MB85RS2MT 256kx8 8pin ~$5 single q.
The Cypress' FM25H20 256kx8 is still expensive ~$20 single q.
The exposed SPI is a good news for me (I do not posses the wp34s yet).
PS: with the FRAM you may emulate the sram (the fram is nonvolatile, with "unlimited" endurance, the write is immediate, no delays) - via the exposed SPI and something like 5-10MHz SPI clock you may achieve a decent r/w speed.
The same works with MRAM - ie Everspin's MR25H40CDC 512kx8 8pin, more expensive ~15$ single q., otherwise the same parameters as the FRAM.
