Micron Memory Part Number — Decoder

: To find total module capacity: (density per chip × number of chips) / 8. But the easier way: look at the number before the letter G . 2G72 is a 16GB module when using modern DDR4 (2G x 72 bits = 16GB). Actually, let's correct: 2G = 2G Bytes? No — in Micron’s lexicon, 2G72 means the module uses 2Gb chips x 72 = 144Gb total / 8 = 18GB? This is confusing.

By following these tips and best practices, users can maximize the benefits of the Micron Memory Part Number Decoder and ensure optimal performance from their system's memory.

This numerical code identifies the specific memory category: Standard DDR4 or DDR5 SDRAM 41: Low-power or specialized DRAM 46: Older DDR/DDR2 architectures 47: DDR3 SDRAM 52: Mobile LPDDR4 / LPDDR5 53: Specialized mobile memory configurations 3. Operating Voltage micron memory part number decoder

The number then includes codes for density, organization, voltage, package type, and speed. For example, a part number like MT40A512M16LY-083R breaks down as follows:

Have a Micron part number you can’t crack? Leave it in the comments (if on a blog platform) or cross-reference with the tables above. When in doubt, request the full datasheet from Micron’s website—it contains the official decoder legend. : To find total module capacity: (density per

for 16 Gigabits). Remember, this is often in bits, not bytes! Configuration : Tells you the data bus width (e.g., x4, x8, or x16 Speed Grade : Look for the suffix after the package code (e.g., for DDR4-3200). Pro Tools for Quick Decoding

MT Type Density Generation Speed Package Temp Process Actually, let's correct: 2G = 2G Bytes

What or FBGA code are you trying to decode?

: Often indicates parts used specifically for Crucial brand modules. : Reserved for engineering samples. 2. How to Use the Decoder Tool To identify a specific chip, use the official Micron FBGA Part Marking Decoder Locate the Code: Find the 5-digit string on the physical chip. Enter the code into the "FBGA Code" field on the website. The tool returns the full Marketing Part Number (e.g., MT40A1G8SA-075:E ), which can then be used to find the Product Data Sheet 3. Anatomy of a Micron Part Number A full Micron MPN (like MT40A1G8SA-075:E ) breaks down into specific segments: : Micron Technology. : Product Family (e.g., 40 = DDR4 SDRAM, 41 = DDR3).

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.
