Micron Memory Part Number Decoder __top__

Micron memory part numbers are comprehensive codes that reveal specific technical details about a component, such as its technology, density, and speed. Because physical chips are often too small for full part numbers, Micron also uses 5-digit FBGA codes for identification. 🛠️ Official Decoding Tools

The most reliable way to identify a component is through official Micron Design Tools.

FBGA/Part Marking Decoder: Use the FBGA Parts Decoder to convert the 5-digit code on a chip (e.g., D9WFL) into a full part number.

SPD Lookup: For memory modules, the SPD Part Number Lookup provides Serial Presence-Detect data essential for BIOS configuration.

Cross-Reference: If you are switching from a competitor, the DRAM Cross-Reference Tool helps find the Micron equivalent. 🔢 Understanding the Part Number Structure micron memory part number decoder

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

Voltage: Typically indicated by a letter (e.g., A for 1.2V in DDR4). Key Identification Guides

DRAM Modules: Refer to the DDR5 Module Part Numbering System or the Legacy DDR4/DDR3/DDR2 Guide for detailed breakdowns of speed bins and configurations.

Storage: Use the SSD Part Numbering System to identify drive interfaces and NAND types. Micron memory part numbers are comprehensive codes that

NOR Flash: Specific details for flash memory can be found in the Serial NOR Flash Guide. 💡 Quick Tips for Identification

Locating the Code: On FBGA chips, look for the second 5-digit code, usually starting with D, C, or Z. Community resources like Reddit's Overclocking Wiki can help identify popular enthusiast chips.

The "TR" Suffix: Often found at the end of a part number (e.g., MT...-0SIT TR), this simply indicates "Tape and Reel" packaging for shipping, as noted on the DigiKey TechForum.

Marking Variations: Full part numbers are often found on stickers on the module, while abbreviated codes are laser-etched directly onto the individual ICs (integrated circuits). If you'd like to dive deeper, I can help you: Decode a specific part number you currently have. MT53E → LPDDR4 2G → 2 Gigabits per

Compare two different speed bins to see which is better for your build. Find the datasheet for a specific Micron component. Which of these would be most helpful for your project?

Real-World Example Walkthrough

Part Number: MT53E2G32D4DT-046 AAT:B

• MT53E → LPDDR4
• 2G → 2 Gigabits per chip (256 MB)
• 32 → x32 data width
• D4DT → Die generation
• -046 → 2133 Mbps (LPDDR4 speed)
• AAT → Automotive Grade (-40°C to 105°C)
• :B → Rev B

Conclusion: An automotive LPDDR4 chip, 2Gb density, x32 wide, running at 2133Mbps.

1. The Prefix (MT)

• MT = Micron Technology
• Legacy note: Older parts may say MT48 (SDRAM/DDR) or MT46 (DDR/DDR2).
