Micron CellularRAM devices are available in several different configurations and densi-
ties (see Figure 3).
After building the part number from the part numbering chart above, visit the Micron
Web site at
the part number is offered and valid. If the device required is not on this list, contact the
factory.
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 www.micron.com/support/decoder. To view the location of the abbre-
viated mark on the device, refer to customer service note CSN-11, “Product Mark/
Label,” at www.micron.com/support/designsupport/documents/csn.
