RE:fpga...programmable vs fixed logic(ptsc).

 "If you're not utilizing the SRAM as the base for the logic, what does that make the flash in this case?"

Normally the programmable logic is a physical trace pattern programed into the SRAM cells.

e.Digital can do it through their overlay logic,  tying together different elements of other logic for applications within flash.  

lets call it...processor functionality....or a mini computer as noted previously.
