Micron Memory Part Number Decoder

Micron uses a standardized prefix system for memory modules (DIMMs, SODIMMs, RDIMMs, LRDIMMs). The general structure is:

Micron uses a highly structured part numbering system to identify memory components and modules. Because physical chips are often too small for full part numbers, Micron also utilizes a five-digit (also known as a D9 code) as an abbreviated identifier.
