What are your issues with the term "non-volatile memory"?

What kind of RAM are you writing to? is it flash memory (ie, it retains its contents when power is removed)? A "solid state disk" sounds like flash memory, but I'm not familiar enough with the term.

IMO, flash memory is a specific type of RAM that has an attribute of being non-volatile, such as any of the memory devices used in removable digital camera memory (including CompactFlash, SD, memory stick, and so on...)

hmmm. I would generally use volatile and non-volatile in terms of software accessible variables. A PROM, or memory structure only accessed by the application, could be considered as non-volatile. However, a register reflecting an external state that could change outside of the software applications direct control (ie, I/O input, thermal sensor, etc.) would be volatile from a software application's point of view.
