This makes sense, and you are right, both parts are labled

about a dozen interesting looking chips, which
are
labled: MK4116E-3
That's the part number of the individual CLCC chips, not
the complete part. The complete part is an MK4332. This appear to
be a 9-pin DIP ceramic carrier with
18 pin 18 contact each, of which only 16 are used. Those are
plain old 16K DRAMs.
So this is a 32k bit DRAM device? (which explains the 18
pins) - I don't recall running across such a beast before.
Been through *LOTS* of 4116 16K DIP DRAMS, and an equally
big number of 4164s over the years...
Actually, now that I think of it, I do have a bag of the
"doubled up" RAM chips from a IBM AT - these look like
two 4116's stacked on top of each other - so these are just
a variation of the same thing ...?
Anyone recognize these? My guess is some sort of
RAM
(dynamic)? Clearly not the same as a standard 4116 DRAM.
Just two of them packaged together. anyone know
what they were used in?
Some PC clones. Some Apple IIIs. Various other stuff.
