I do not understand the question. You can buy parts that are 8 bits by 512 which is 512 bytes. Static RAM by it's nature is fairly self contained with little in additional circuits since it does not require refresh.
512/1.6=320 MPH
512 MB of photo space.
512 cubic centimetres or 512 millilitres.
200
.512 inches
Assuming a 512 MiB DIMM of RAM is ~50 grams, 8 GiB of RAM would be ~800,000 milligrams. If you instead meant "How many MiB make 8 GiB", then the answer would be 8192.
85.3333
Quite possibly 512 cubic inches!
The only difference would be if your motherboard has dual channel capability. Check your manual to see. If it does then 2 x 256MB would be the faster option.
