Micron Memory Part Number Decoder

Micron memory part numbers

Here’s a helpful guide to decoding (for DRAM, NAND, and DDR modules). Micron (which includes the Crucial brand) uses a structured numbering system. Once you understand the key fields, you can identify density, speed, generation, package, and more.

Once you have that 5-digit code, you can get the full part number (which usually starts with ) using Micron's official tool: Micron FBGA Part Marking Decoder micron memory part number decoder

found physically on memory chips. To bridge this gap, Micron provides the FBGA and Component Marking Decoder Micron memory part numbers Here’s a helpful guide

Limitations and Variations

• Micron’s public documentation may omit some internal assembly/revision suffix meanings.
• New product lines (e.g., DDR5, advanced NAND) add new codes—always verify with current datasheets.
• Some codes overlap across families; misidentifying the family yields wrong decoding.
