chitech's (actually Seatron's) 30mm x 70mm SO-DIMM has 2 memory chips
on one side (total of 256mb), and there are 2 unpopulated on the
*other* side of the SO-DIMM (which you can't see from the photo of the

... $EUR 99 had better not be the mass-volume price of the SO-DIMM,
though, even if they can do 1200mhz. the 833mhz Samsung ARM Cortex A8
S5PC100 is $14.50 (and 256mb of DDR2 RAM works out at around $10)
which brings an entire S5PC100-based SO-DIMM in at somewhere around
$32 to $35.
but, yeah: if they already _have_ an SO-DIMM with the kirkwood 88F6281
then that's better than actually having to do a complete design from
... time to market etc. etc.
