I've interviewed a lot of different people from a lot of different Universities and I agree a lot of schools treat that as part of Computer Engineering. My undergrad was also accredited as an engineering program which may have something to do with it. But with that said, I've seen a lot of CS programs that also have at least some of those courses.

Also, some schools blur CS and Electrical Engineering and for those you may take a whole other set of courses neither of us mentioned.
