A PCI-attached SSD is very much not memory;

Right, I didn't mean memory like a computer's main memory. I meant like electronics that remembers.

If you have an acronym you prefer, please use it, but people generally call such devices SSDs.

I don't believe people do generally call that setup SSD. I encounter solid state storage a lot in my job and though I do sometimes see people use the term that way, they usually get corrected by someone who points out they'll cause unnecessary confusion, since the issues surrounding solid state emulated disk drives are so much different from those surrounding other deployments of persistent electronic memory.

In fact, now that I think of it, I'm pretty sure SSD implies not only ATA etc electronic interface, but a form factor that lets you plug one into a frame intended for a disk drive. E.g. the CompactFlash "memory card" you put in a camera is not called an SSD, but has a SATA interface at the electronic level.
