Ramp rate with 50ohm?

Hi, every body. This is the first time I ask this question
to IBIS forum after I joined yesterday.

I am a memory designer and starts wondering why we have to
provide ramp rate data with "non reactive 50ohm" attached
to output buffer.
Once we provided ramp rate to a customer and he asked us to
attach 50ohm to output buffer.
Why is that? Is it so crucial?
Hope I can clarify this issue from all of you.
Thanks.
