Micron Memory Part Number Decoder |verified| May 2026

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.

72 indicates an ECC (Error Correction Code) module (64 data bits + 8 ECC bits).
64 indicates a non-ECC module.

: The primary tool for translating 5-digit chip markings (e.g., "D9VPP") into full Micron Part Numbers (MPN) . micron memory part number decoder

Decoding Micron memory can be tricky because the number physically printed on the chip (the Micron memory part numbers Here’s a helpful guide

After the G (72) = Total data width in bits.

: The decoder is specifically for FBGA-packaged components. Standard modules (like DIMMs) typically use a Serial Presence-Detect (SPD) Lookup Mobile Experience 72 indicates an ECC (Error Correction Code) module
