Open Question: petsmart rehire policies?

I worked for petsmart for four and a half months in 2009. I told my boss that i was quitting because I had some issues with another manager and I had found another job that I hope would allow me to advance farther than they would because of my situation. My boss put me down as not rehireable. and he didn't really give me a reason other than that I chose not to put in my two week notice. so my question is... 1. can he legally do that? and 2. if i'm put down as not rehireable, does that mean for a certain period such as a year or two years? or never for the rest of my life?
