FPGA is RAM based technology. Even if you want to use it for any custome design you have you need to have PROM with that. You can reuse it. But as soon as you power off the circuitary that will loose the program and for next start it has to get booted through the PROM You will attach.
Both FPGA and PROM can be burned through same kit.

That means whatever i design it will be first loaded in the PROM which is programmable. so if i make different design for my project i need not have to buy different FPGA to implement them individually i can use same FPGA.
Notice that all Xilinx FPGAs use SRAM to store the interconnects,
so are reprogrammable,
but volatile (thus requiring external ROM). On the other hand,
Actel FPGAs are non-volatile (they use antifuse),
but are non-reprogrammable (except one family, which uses Flash memory).
Since each approach has its own advantages and disadvantages,
the actual application will dictate which chip architecture is most
appropriate.
FPGA,s are reprogrammable and can can be programmed again and again. it is not like ASIC. as u said it is like rewritable CD. and u need to have software like XILINX for programming and erasing and again programming

u can use a fpga llike a rewrittable cd.
U can use fpga which is reprogrammable and non-volatile from Lattice .
