This makes sense, and you are right, both parts are labled
identically... I can't find a "whole device" part number.

Yes - I counted one side and failed to x2 before posting.

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 ...?

Thanks.
