I wonder if I could have a reality check here. The thing that's 
bothering me is that, for example, a CompactFlash card looks like an 
IDE/ATA disc hence must have internal firmware handling wear levelling. 
Similarly, an MMC card with a matched host controller looks like a 
storage device so presumably the same applies.

But what is the situation with an MMC card in isolation, being driven by 
bit-banging or by code in e.g. a BASIC Stamp using SPI? Do these still 
look like discs?

Going back to the OP's question, there certainly used to be things like 
battery-backed SRAM cards that fitted in a PCMCIA slot, if I recall 
correctly Sun used them to move configuration information between 
computers. Does anybody put bare Flash into a similar outline, i.e. 
relying on the kernel and drivers to handle all housekeeping?
