If you want, provide a specific Micron part number and I’ll decode it for you.

Decoding a Micron memory part number reveals critical specs like technology (DDR4/DDR5), density, and speed grade. Because chips are often too small for full part numbers, they use a 5-digit FBGA code (e.g., D9VPP) that you must decode first. 1. Essential Decoding Tools

FBGA & Component Decoder: Enter the 5-digit code found on the physical chip to get the full "MT" part number.

DRAM Cross-Reference Tool: Compare specific Micron part numbers against competitors or find exact technical specs. micron memory part number decoder

SPD Data Lookup: Get detailed timing and configuration data for a full module. 2. Standard Part Number Breakdown (DRAM)

Most Micron DRAM part numbers follow this pattern: MT [Technology] [Configuration] [Package] - [Speed] [Revision]. Common Codes Definition Technology 40 (DDR4), 60 (DDR5), 41 (DDR3) The generation of memory. Configuration 1G8 (8Gb x8), 512M16 (8Gb x16) Depth (density) and data bus width. Voltage A (1.2V), B (1.1V), K (1.35V) Operating voltage requirements. Speed Grade -062E (DDR4-3200), -075 (DDR4-2666) Max frequency and timing (CL-tRCD-tRP). Die Revision :E, :B, :A The specific manufacturing "generation" or "die". 3. Key Suffixes & Markings FBGA and part decoder | Micron Technology Inc.

Micron utilizes a specialized part numbering system that differs between full Marketing Part Numbers (MPN) and abbreviated FBGA Marking Codes

found physically on memory chips. To bridge this gap, Micron provides the FBGA and Component Marking Decoder

tool to convert short codes into complete, searchable part numbers. 1. FBGA Marking Code vs. Full Part Number

Because of physical space constraints on small memory packages, Micron cannot print the entire MPN on the chip. Instead, they use a five-digit alphanumeric code

This code is typically the second five-digit mark on the chip, often found on the middle or bottom row of text. Common Prefixes: : Standard production parts (e.g., D9WFL).

: 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). | Field | Code | Meaning | |-------|------|---------|

: Density and Configuration (e.g., 1Gb capacity with x8 width). : Package Code (FBGA/BGA type). : Speed Grade (Clock rate/MT/s target).

: Operating Temperature (e.g., IT = Industrial, blank = Commercial).

: Die Revision (Designator for specific internal silicon version). 4. Additional Decoder Resources

The Ultimate Guide to the Micron Memory Part Number Decoder In the world of high-performance computing, the string of characters etched onto a RAM chip or printed on an SSD label isn't just a serial number—it’s a dense, encoded biography of the hardware. Whether you are a system builder, an overclocker, or a curious tech enthusiast, understanding the Micron part number decoder

is the key to identifying a component's generation, speed, and capabilities at a glance. The Challenge: Marketing Part Numbers vs. FBGA Codes

Micron uses two distinct identification systems that often confuse users: Marketing Part Number (MPN): The full identifier (e.g., MT40A512M16LY-083R:H ). These are found on module labels and invoices. FBGA Code: A short, 5-digit alphanumeric code (e.g.,

) laser-etched directly onto the tiny memory chips because the full MPN won't fit. To bridge this gap, you can use the official Micron FBGA and Component Marking Decoder Part Number: MT53E2G32D4DT-046 AAT:B

. Simply enter the 5-digit code to reveal the full part number and technical specifications. Breaking Down a Micron Part Number

While each product family (DDR4, DDR5, NAND) has its own specific logic, most follow a standardized structure: 1. The Core Prefix: MT Every Micron part begins with , which stands for "Micron Technology". 2. Product Family The numbers following "MT" identify the technology type: DDR4 SDRAM DDR3 SDRAM DDR5 SDRAM (Current generation) NAND Flash Solid State Drive (SSD) 3. Configuration and Density

After the product family comes the capacity and width. For example, indicates a density of 512 Megabits with a 16-bit wide bus. 4. Speed Bins and Latency The segment after the hyphen (e.g., ) tells you the performance rating. Refers to DDR4-2400 (1200 MHz). Common in DDR5, indicating specific JEDEC speed bins. 5. Die Revision (The "Binning" Secret) The letter at the very end (e.g., Die Revision

. For overclockers, this is the most critical part. Certain revisions, like the legendary (D-die) or

(E-die), are famous for their ability to handle higher frequencies and tighter timings than standard chips. Interactive and Advanced Tools

If you are looking for more than just a manual lookup, Micron provides specialized resources: Design tools | Micron Technology Inc.

Decoding Micron Technology memory part numbers can be complex because the format varies significantly between product families (e.g., DRAM vs. NAND Flash vs. Managed NAND). However, the most common decoding requests involve DRAM (DDR4, DDR5) and NAND Flash components.
