"burning" fpgas: fpgas (normal ones, there is always an exception) use an sram or a flash memory to hold a binary of your design. the sram is erased when you power off the board, the flash is erased when you give the command to erase it. when the memory is cleared you can reprogram the fpga. you can order single fpga chips, but you dont need them (only if you want to build your own board)
