Can I change how much ram my graphics card uses?

I have a laptop that runs Windows 7 64-bit, 4GB of ram, and a 250 GB hard drive, but the problem is have a pretty bad graphics card, the standard/default Intel Graphics HD Family. It runs pretty well, but lags an s-ton when I play Minecraft. Is there a way for me to change how much ram the graphics card uses, to borrow from the motherboard, since I have 4 gigs of ram? I don't know much about computers outside of high school computer class, so sorry if I sound like a butthole.

It by default uses motherboard ram since it's integrated graphics

Yes you will have to go into your laptop bios and change it.
