Number Decoder — Micron Memory Part

Understanding the Micron Memory Part Number Decoder Micron Technology utilizes a sophisticated part numbering system that provides detailed specifications for every memory component, from consumer DRAM to enterprise SSDs. Because physical space on a chip is limited, Micron also uses abbreviated FBGA codes (often starting with "D9") to identify parts on the manufacturing floor. 1. Decoding FBGA Marking Codes

Micron's full part numbers (e.g., MT40A512M16LY-062E:E) follow a hierarchical format. Detailed guides are available for different product families. Common Memory Prefixes & Codes MT: Stands for Micron Technology. Product Family: 40: DDR4 SDRAM 41: DDR3 SDRAM 47: DDR2 SDRAM 60: GDDR6 micron memory part number decoder

: 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).

Another example: embedded systems often require low-power LPDDR4X. Part number “MT53E1G32D2FW-046” decodes as: LPDDR4X, 1G x 32 (32Gb density), “046” = 4.266 Gb/s. Using a standard DDR4 part instead would break power and signal integrity. Decoding FBGA Marking Codes Micron's full part numbers (e
