Micron Memory Part Number Decoder [repack]

Micron offers supplemental guides for specific product categories: FBGA and part decoder | Micron Technology Inc.

: Micron Solid State Drive (e.g., 2400, 3400, or 7450 SSD series).

: Useful for finding compatible replacements for DRAM and LPDRAM components. DRAM Component Decoding (Structure) micron memory part number decoder

: Subsequent die shrinks or optimizations. For overclockers and system builders, the die revision (like Micron "E-die" or "B-die") is highly prized for its unique voltage scaling and timing characteristics. Micron FBGA Overmarking (The 5-Digit "FBGA Code")

[MT] [40] [A] [1G8] [SA] - [062E] : [E] | | | | | | | 1 2 3 4 5 6 7 1. Brand Identifier DRAM Component Decoding (Structure) : Subsequent die shrinks

: Highly optimized, mature production revision (frequently prized by overclockers for stability).

: Use the FBGA Parts Decoder to convert the 5-digit code on a chip (e.g., D9WFL) into a full part number. 40 = DDR4 SDRAM

1 Gigabit total capacity, organized as x8 (8 bits wide).

: 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).

The complete technical string (e.g., MT40A512M16LY-062E:E ) used for ordering and locating datasheets. 2. How to Read Micron Part Numbers
