If you buy eMMC IC first hand - mostly they may be are empty and you need to fill it ( via JTAG or direct eMMC connection ). In third party suppliers ( most chinese web-shops ) eMMC are already partialy preprogrammed ( even just with boot-s ) depend of target market / i9300, N7100 ect ... / .

In any case if you have separate eMMC and eMMC programming slot is good idea to rewrite eMMC contain according to your needs BEFORE to solder it it to PCB - this will test a eMMC health and will prevent you from mistakes.
