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
: Defines the specific memory architecture (e.g., DDR4, DDR5, LPDDR5).
Decoding Micron Memory Part Numbers: A Complete Guide Understanding these codes is essential for engineers, procurement officers, and tech enthusiasts who need to source, replace, or verify Micron technology. Because Micron continuously updates its naming conventions across different product lines—such as DRAM, NAND Flash, and Solid State Drives (SSDs)—using a systematic decoding approach prevents costly compatibility errors. The Structure of a Micron Part Number
: The full tracking string used for ordering and datasheets (e.g., MT40A2G8AG-062E:B ). micron memory part number decoder
: Used in DDR5 to denote specific MT/s ratings (e.g., DDR5-4800). 8. Die Revision (:E)
Micron part numbers are broken down into specific fields, where each position or group of characters represents a distinct hardware attribute. While the exact meaning of each position shifts depending on whether the component is volatile memory (DRAM) or non-volatile memory (NAND), the overall architecture remains consistent.
Understanding how to read a Micron memory part number decoder gives you the ability to catalog inventory accurately, diagnose system hardware limits, and prevent costly purchasing mistakes. Bookmark this framework or keep Micron's digital FBGA tool handy to instantly identify any Micron chip that crosses your bench. This numerical code identifies the specific memory category:
This guide breaks down Micron’s part number numbering system so you can accurately decode any Micron memory component. Why Decoding Micron Part Numbers Matters
Micron provides an official FBGA and Component Marking Decoder to convert this short code into a full part number. 2. Breaking Down the Part Number (Documentation Level) Once you have the full part number (e.g., MT40A512M16LY-083R:H
On smaller memory chips, there is not enough physical surface area to print the full 12 to 18-character part number. To solve this, Micron prints a , known as the FBGA code . and operational voltages before installation.
: Typically indicated by a letter (e.g., A for 1.2V in DDR4). Key Identification Guides
If you need help identifying a specific component, please share the or the 5-digit FBGA code printed on your chip. I can also break down the precise pin layout or timing latencies for a particular memory generation if needed. Share public link
Confirm speed grades, densities, and operational voltages before installation.
