If you have a partial or heavily scrubbed part number, look for Micron's (a 5-digit alphanumeric code usually printed in the center of smaller chips). Micron provides an online FBGA-to-Part-Number reverse lookup tool on their official website to help convert these short codes back into full part numbers.

Before diving into the syntax, understand the stakes. Two memory modules can look identical physically but have entirely different electrical characteristics. For example, a Micron module labeled MTA18ADF2G72AZ is a 16GB DDR4 ECC registered DIMM. Change one character— MTA18ASF2G72AZ —and it becomes a unbuffered DIMM. Plugging the wrong one into a server motherboard might prevent POST (Power-On Self-Test).

Locate the 5-digit code printed on the top surface of the IC (Integrated Circuit). It usually starts with a letter like "D9" for DRAM or "NW" for NAND.
