Micron Memory Part Number Decoder -

Directly following "MT" are the characters indicating the specific class of memory. : DDR4 SDRAM 60B : DDR5 SDRAM 41K : DDR3L SDRAM (Low Voltage 1.35V) 46V : DDR1 SDRAM 47H : DDR2 SDRAM 53D : LPDDR4 / LPDDR4X Mobile RAM 62M : LPDDR5 Mobile RAM 3. Configuration and Density

But here’s the secret: They are highly structured, logical, and once you learn the "grammar," you can identify the density, speed, voltage, and even the temperature rating in under 30 seconds.

Micron uses two different types of codes on their chips. They use standard part numbers and short FBGA code aliases.

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)

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 micron memory part number decoder

[MT] [40A] [1G8] [SA] - [062E] : [E] ── ─── ─── ── ──── ─ 1 2 3 4 5 6

If the memory is designed for rugged environments, a temperature indicator will be present before the colon: : Commercial temperature range (0°C to +95°C) IT : Industrial Temperature range (-40°C to +95°C) WT : Wireless/Extended Temperature range (-40°C to +105°C) AT : Automotive Temperature range (-40°C to +105°C) 8. Die Revision (The "Die Generation")

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 (e.g., D9VPP) that you must decode first. 1. Essential Decoding Tools

The letters near the end show the physical shape of the chip and its design version. Directly following "MT" are the characters indicating the

Identifies whether the drive utilizes SLC (Single-Level Cell), MLC, TLC, or QLC (Quad-Level Cell). This tells you the endurance and write-lifecycle expectations of the drive.

: 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.

FBGA and part decoder | Micron Technology Inc.

Micron makes memory chips for computers, phones, and servers. Each chip has a long string of letters and numbers printed on it. This text is called a part number.

: 2 Gigabits total capacity, configured with a 4-bit wide data bus. Micron uses two different types of codes on their chips

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.

Micron Technology. This prefix is standard across virtually all genuine Micron components. 2. Product Family / Technology

By mastering the principles, you can ensure that the component you have matches the requirements of your design, preventing technical issues during development. For the most accurate, up-to-date data, always use Micron’s official Part Numbering Guide.
