Micron Memory Part Number Decoder | 2026 Update |

The Ultimate Guide to the Micron Memory Part Number Decoder In the world of high-performance computing, the string of characters etched onto a RAM chip or printed on an SSD label isn't just a serial number—it’s a dense, encoded biography of the hardware. Whether you are a system builder, an overclocker, or a curious tech enthusiast, understanding the Micron part number decoder

is the key to identifying a component's generation, speed, and capabilities at a glance. The Challenge: Marketing Part Numbers vs. FBGA Codes

Micron uses two distinct identification systems that often confuse users: Marketing Part Number (MPN): The full identifier (e.g., MT40A512M16LY-083R:H ). These are found on module labels and invoices. FBGA Code: A short, 5-digit alphanumeric code (e.g.,

) laser-etched directly onto the tiny memory chips because the full MPN won't fit. To bridge this gap, you can use the official Micron FBGA and Component Marking Decoder

. Simply enter the 5-digit code to reveal the full part number and technical specifications. Breaking Down a Micron Part Number

While each product family (DDR4, DDR5, NAND) has its own specific logic, most follow a standardized structure: 1. The Core Prefix: MT Every Micron part begins with , which stands for "Micron Technology". 2. Product Family The numbers following "MT" identify the technology type: DDR4 SDRAM DDR3 SDRAM DDR5 SDRAM (Current generation) NAND Flash Solid State Drive (SSD) 3. Configuration and Density

After the product family comes the capacity and width. For example, indicates a density of 512 Megabits with a 16-bit wide bus. 4. Speed Bins and Latency The segment after the hyphen (e.g., ) tells you the performance rating. Refers to DDR4-2400 (1200 MHz). Common in DDR5, indicating specific JEDEC speed bins. 5. Die Revision (The "Binning" Secret) The letter at the very end (e.g., Die Revision

. For overclockers, this is the most critical part. Certain revisions, like the legendary (D-die) or

(E-die), are famous for their ability to handle higher frequencies and tighter timings than standard chips. Interactive and Advanced Tools

If you are looking for more than just a manual lookup, Micron provides specialized resources: Design tools | Micron Technology Inc.

Micron’s part numbering system is logical, but it’s dense. Once you memorize the prefix (MT40A = DDR4, MT53E = LPDDR4) and the speed codes (-062E = 3200), you’ll read these like a native.

Pro move: Bookmark Micron’s official Part Marking Decoder (free, no login required). Enter your string, and it spits out density, speed, voltage, and a direct datasheet link.

Introduction

Micron Technology is a leading manufacturer of memory and storage products, including DRAM, SRAM, Flash, and other types of memory. Micron's product portfolio is vast, with thousands of different part numbers across various product lines. Decoding these part numbers can be a daunting task, especially for engineers, procurement specialists, and distributors who need to identify and source specific memory components. This paper aims to provide a comprehensive guide to decoding Micron memory part numbers, enabling readers to understand the structure and meaning behind these part numbers.

Micron Part Number Format

Micron's part numbers follow a standardized format, which consists of several segments that convey specific information about the product. The format typically consists of 8-12 characters, depending on the product type. The following is a breakdown of the typical Micron part number format:

[Product Family] [Product Type] [Density] [Speed] [Package] [Temperature] [Other Options] micron memory part number decoder

Let's examine each segment:

  • Product Type: This segment specifies the product type within the family, such as:
  • Density: This segment represents the memory density, usually in megabits (Mb) or megabytes (MB). For example:
  • Speed: This segment indicates the product's speed or performance, usually represented by a number and a letter (e.g., 133M, 266M). The speed segment may also include additional information, such as:
  • Package: This segment describes the product's packaging, including:
  • Temperature: This segment indicates the product's operating temperature range:
  • Other Options: This segment may include additional information, such as:
