Hey, interesting, those are almost identical. Yeah, I'm not sure "hybrid"
was really the correct term, maybe MCM? I see a couple components attached
to a piece of ceramic and I want to call it a hybrid... probably have been
looking at too many RF component databooks recently, LOL.

Thanks for noticing the similarity and posting... I guess those modules are
almost certainly some kind of memory? It's just such an unusual packaging
scheme for it.
