Micron Memory Part Number Decoder [better] Guide

Prefix indicating Micron manufacturer. 40 (Product Family): 40: DDR4 SDRAM 41: DDR3 SDRAM 53: LPDDR4/LPDDR5 62: Mobile LPDDR2 A (Voltage): A: 1.2V (DDR4) B/C/D/K: Other voltages (e.g., 1.35V DDR3L) 1G8 (Configuration): 1G: Density ( 8: Bus width ( ×8cross 8 S (Revision): Die revision (e.g., A, B, C). A (Package): Defines physical FBGA package. -062E (Speed/Latency): -062E: DDR4-3200 (0.625ns) -075: DDR4-2666 (0.75ns) IT (Operating Temperature): Blank: Commercial ( IT: Industrial ( AT: Automotive ( or higher) :E (Die Revision): Final component revision designator.

512 Megabit depth x 16-bit width (Totaling an 8Gb chip). 5. Package Codes (Mechanical Layout)

Enter the 5-digit code to reveal the full MT... part number. 💾 Section 3: Decoding Micron NAND Flash Part Numbers micron memory part number decoder

Following the hyphen, this code indicates the maximum speed the memory can safely achieve. Micron uses exact nanosecond ratings or megatransfers (MT/s) markers:

Identify the (e.g., 40A for DDR4, 60B for DDR5) to check device generation compatibility. Prefix indicating Micron manufacturer

Once you have the full part number from the decoder, you can break it down to understand its specifications. The structure varies slightly between DRAM and Flash memory. Let's explore both.

Look closely at your hardware. If you are looking at a bare RAM chip on a graphics card or memory stick, write down the 5-digit FBGA code. If you are looking at a sticker on a server DIMM, find the long "MT" part number. Step 2: Use Official Micron Tools -062E (Speed/Latency): -062E: DDR4-3200 (0

Modern DDR4 parts, like the MT40A512M16LY-083R or MT40A1G16WBU-083E , have evolved to include details like density (512M or 1G depth), data width (x16), and specific speed ratings like 083E .

The final characters after a colon or space denote the silicon revision (Die Generation) and environmental tolerances.
