All SRAM based FPGAs download their date from a FLASH based EEPROM at start up, via JTAG, SPI or parallel interface. You have some basic info at:

FPGA's r volatile. But FPGA's have either an on Chip PROM or external PROM to have the configuration file. Once its powered up FPGA loads the configuration file from the PROM and starts working once configuration is done.
