Due to the size of the package, the Micron-standard part number is not printed on the
top of the device. Instead, an abbreviated device mark consisting of a five-digit alphanu-
meric code is used. The abbreviated device marks are cross-referenced to the Micron
part numbers at the FBGA Part Marking Decoder
