Note:
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, please go to the Micron
Part Marking Decoder Web site at
part number is offered and valid. If the device required is not on this list, please 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 comprised of a five-digit alphanu-
meric code is used. The abbreviated device marks are cross-referenced to the Micron
part numbers at http://www.micron.com/partsearch. To view the location of the abbre-
viated mark on the device, please refer to customer service note, CSN-11, “Product
Mark/Label," at http://www.micron.com/csn.
