This question is more suitable in fpga newsgroup. The reason is that your
VHDL synthax is correct but Spartan may not have so many FF registers. It
may embody a general purpose memory though. Each cell of typical FPGA has
only one configurable FF register in addition to configurable and
service(that performs configuration) logic. This makes FPGA cell a very
expensive resource. Therefore, a dedicated storage device is much more
robust to keep high volume infrequently issued data. Check out SpartanII
specs and examples to know how make use of it.
