: 1 Gigabit depth x 8-bit width (8 Gb total chip density)
Micron solves this by using a special FBGA Code. This is a short, five-character code printed on the component's top marking. If you search the internet for this code, you likely won't find anything, as it is not the part number.

Locate the 5-digit code printed on the top surface of the IC (Integrated Circuit). It usually starts with a letter like "D9" for DRAM or "NW" for NAND.
Micron memory part numbers are a unique identifier assigned to each memory module produced by the company. These part numbers contain a wealth of information about the memory module, including its type, capacity, speed, and features. A typical Micron memory part number consists of a combination of letters and numbers that can be broken down into several sections. micron memory part number decoder
A standard Micron DRAM component part number (e.g., MT48LC16M8A2TG-75 ) consists of distinct fields:
If you have a partial or heavily scrubbed part number, look for Micron's (a 5-digit alphanumeric code usually printed in the center of smaller chips). Micron provides an online FBGA-to-Part-Number reverse lookup tool on their official website to help convert these short codes back into full part numbers.
Learning to decode Micron’s part numbers saves you from costly compatibility errors and helps you source exact replacements in seconds. While the system looks intimidating at first glance, it follows strict JEDEC and internal logic. Memorize the core segments:
Micron's full part numbers (e.g., ) 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 : 1 Gigabit depth x 8-bit width (8
: The full tracking string used for ordering and datasheets (e.g., MT40A2G8AG-062E:B ).
: Typically indicated by a letter (e.g., A for 1.2V in DDR4). Key Identification Guides
Micron uses a standardized prefix system for memory modules (DIMMs, SODIMMs, RDIMMs, LRDIMMs). The general structure is:
: Enter your 5-digit code in the "FBGA Code" field to reveal the full MT part number. Step 3: Decode the Full Part Number (The "MT" Code) Once you have the full part number (e.g., MT40A512M16LY-083R:H ), here is how to read it: Micron Technology Product type (e.g., 40 = DDR4, 60 = DDR5, 41 = DDR3) Operating voltage (e.g., A = 1.2V) 512 Megabits x 16-bit width (8Gb total) Physical package code (e.g., 96-ball FBGA) Speed grade (e.g., -083 refers to DDR4-2400) Design generation/Die revision (e.g., H-die) Useful Deep-Dive Resources For Desktop/Laptop RAM: Micron Module Part Numbering Guide (PDF) explains how to decode entire RAM sticks (DIMMs/SO-DIMMs). For Individual Chips: DRAM Component Part Numbering System covers raw chips like DDR4, DDR5, and LPDDR.

Almost all Micron component part numbers begin with the prefix . This simply stands for Micron Technology. 2. Memory Product Type
for 16 Gigabits). Remember, this is often in bits, not bytes! Configuration : Tells you the data bus width (e.g., x4, x8, or x16 Speed Grade : Look for the suffix after the package code (e.g., for DDR4-3200). Pro Tools for Quick Decoding
However, the full part numbers can be long, and the physical markings on the chips (FBGA codes) are often abbreviated due to space constraints. This article acts as a , providing a step-by-step guide to interpreting these codes, along with methods for decoding abbreviated FBGA markings.
Indicates the total capacity of the chip package (e.g., = 128 Gigabits, 1T = 1 Terabit). Keep in mind this is in gigabits, not gigabytes (8 Gigabits = 1 Gigabyte). 3. Device Configuration (08)
Once you have that 5-digit code, you can get the full part number (which usually starts with ) using Micron's official tool: Micron FBGA Part Marking Decoder
