Most of Micron’s component products use one of two product mark variations to accommodate
smaller components and different package sizes (for example, FBGA and CSP).
Both product marks are right- and left-justified and have a character height of 0.040–
0.050 inches depending on package size. Both marks also include a unique, laserinscribed
identification number on the top side of the part for traceability purposes.
Legacy component products with Elpida part marks use the same part marks used prior
to Micron's acquisition of Elpida. Further information may be found in our product
guides and on Micron’s Web site: www.micron.com/numbering
