I have a chance to pick up a sealed brick of DDR chips, which would be
handy for a project I'm working on. However, there's no manufacturer
information on the packaging, and I have had zero luck searching up any
other info (Google and such) on what part information I have.

The label on the brick says:

Part No.: K321602BT-H-A
Item Code: 32*16 DDR TSOP

So I'm pretty sure these are 32M X 16 DDR SDRAM chips (8 of them on a 512
MB DIMM). However, without a pinout and preferably a datasheet they won't
be much use.

I have seen a loose chip, but there are no meaningful markings on the chip
(nothing resembling a part number).

The chip package is a 50 pin TSOP (pins on the two long edges). So if you
have a loose DDR DIMM laying around and feel like counting the pins to see
if the chips are 50 pinners, that could lead to some useful info.

In my searching, I found that Samsung chips of the suspected capacity have
66 pins. Micron chips of this capacity have 54 (or was it 56) pins. I
suspect that if I can find a similarly organized chip by a known company,
in the 50 pin package, that the pinout will probably be the same. Of
course, I still won't have speed information, but my application doesn't
require super high performance.

I would appreciate any information or pointers (or funny jokes) anyone out
there can provide. No matter how good a deal I could get on the brick,
it's worthless unless I have enough information on the chips to use them.
The current owner says he got them in a lot with some other stuff.

Thank you for any helpful or humorous suggestions.
