Hi Mike- missed this. We've had the SRAM/FRAM/FLASH boards built up since the EEPROM board was released, but have not had time to release those- we're hoping to do so early in the year after we increase our staff a bit. The 1Mbit FRAM will definitely be more expensive than the EEPROM unfortunately! The part cost is roughly 3x at low volume. I think the SRAM(1Mbit) and FLASH(8Mbit) can be the same relatively low cost as the EEPROM.
