Yes, two pins seems fine, one pin an unnecessary constraint.

But may still be rather expensive in absolute terms.  Really I'm not
sure I even see a use for 2M of ram in a thing like this.  The 256k (I
guess that's words rather than bytes) in the GA eval board seems like
more than plenty.  As Bill Gates said, 640k should be enough for anybody
;-).
