Thomas,

Xilinx FPGA are RAM based; so, is configured ( not programmed ) writing 
a bitstream into the configuration RAM via JTAG, unlimited; but after 
development stage  the bitstream is saved into a another device as a 
FLASH memory, microcontroller, hard disk, etc.. This storage device 
could have a limited erase/write cycles, theoretically 100.000 cycles 
for FLASH based devices.
