: Allows users to find technical specs by entering a DRAM module part number .
: You can translate these codes back into full part numbers using the Micron FBGA and Component Marking Decoder . 2. Micron DRAM Part Numbering System micron memory part number decoder
: 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. If you are looking at a hard drive, use the Micron SSD Part Numbering Guide Do you have a specific code from a chip that you're trying to identify right now?

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:
JY, BD, RC). It affects timing parameters and power, but you typically don’t need to memorize these.
