Micron Memory Part Number Decoder !new!

Understanding a Micron memory part number is essential for identifying the exact specifications of RAM or SSD components. Because physical space on a chip is limited, Micron uses shorthand "FBGA codes" (often starting with D9) that require an official decoder to translate into a full part number. Using the Official Decoder Tools

Decoding Micron Modules (DIMMs vs. Components)

If you have a stick of RAM (DIMM) like MTA18ASF2G72AZ-3G2R, the rules change: micron memory part number decoder

Mark/Bit Cell: Identifies the technology, such as A for SLC (Single Level Cell). Understanding a Micron memory part number is essential

6. Revision and Special Flags
The colon and “B” denote the die revision. This is crucial for tracking errata, power changes, or timing improvements. Revision letters are sequential (A, B, C…). Sometimes an “IT” appears before the revision, signifying Industrial Temperature range (-40°C to +95°C) instead of Commercial (0°C to +95°C). An “A” at the end might indicate automotive grade. Components) If you have a stick of RAM

Z9...: Typically designates Engineering Samples (ES) not yet meant for mass production. FBGA and part decoder | Micron Technology Inc.

For example, consider the part number "MTA18ASF2G72PZ-2G3B1":

4. Speed Grade (-2E3)

This is the most critical number for performance compatibility. Micron uses a specific digit to represent the transfer rate in MT/s (MegaTransfers per second).
