hello may some one tell me which rom uses less system ram and internal memory.

Doing an analysis like that would probably take weeks and a decent lab. I doubt anyone's interested enough to do it for free.

Stock non rooted ROM, pretty much the way how you bought the phone, or you can try other Roms that are available, and see for yourself.
