Micron Memory Part Number Decoder |link| -

Micron FBGA and Part Marking Decoder is an essential technical utility for hardware engineers, repair technicians, and enthusiasts who need to identify specific memory chips. Because FBGA-packaged components are too small to fit a full marketing part number, Micron uses a shorthand 5-digit code (the "FBGA code") laser-marked on the chip. Key Features Abbreviation Translation

: It acts as a bridge between the physical marking on a chip (e.g., a five-digit alphanumeric string like "D9WFK") and the official Marketing Part Number (MPN) Data Sheet Access

: Once the full part number is retrieved, the tool often provides direct links to the relevant data sheets for technical specifications like voltage, density, and speed. Comprehensive Database

: The decoder covers a wide range of Micron products, including DRAM (DDR4, DDR5), NAND Flash, and SSD components. Ease of Use

: The interface is straightforward—you simply enter the 5-digit code found on the chip (usually preceded by an "MT" mark) to get immediate results. : Using the official Micron FBGA Part Decoder

ensures you aren't relying on third-party spreadsheets or outdated forum posts. Cross-Compatibility

: It supports both active and obsolete part catalogs, making it useful for servicing legacy hardware. Limitations Package Dependency

: The decoder is specifically for FBGA-packaged components. Standard modules (like DIMMs) typically use a Serial Presence-Detect (SPD) Lookup Mobile Experience

: While functional, the official tool is optimized for desktop technical use; identifying tiny laser marks on physical chips remains a manual, often difficult prerequisite. The Micron Part Number Decoder is a mission-critical tool

for anyone working at the component level. While casual consumers might find it overly technical, it is the only definitive way to verify the exact specifications of a Micron chip without secondary software. part numbering guide for a specific memory type (like DDR5 or NAND)?

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

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:

Let's examine each segment:

1. Product Family: This segment identifies the product family, such as:
   • MT (DRAM)
   • MX (Flash)
   • MR (SRAM)
   • MD (DRAM modules)
2. Product Type: This segment specifies the product type within the family, such as:
   • DRAM: SDR, DDR, DDR2, DDR3, DDR4, etc.
   • Flash: NOR, NAND, etc.
   • SRAM: Async, Sync, etc.

🔍 Micron Part Number Decoder – Key Fields

Most Micron memory components (like DDR4, DDR5, LPDDR, NAND) follow a format like:

MTxxxxxxx_xx_xx_xxxx-xx

Below is the breakdown for DRAM components (the actual chips on a module). Product Family : This segment identifies the product

3. The Density (512M)

This is the per-chip density, not the module size.

• 512M = 512 Megabits
• 1G = 1 Gigabit
• 8G = 8 Gigabits

Pro tip: To get the total chip capacity in Gigabytes, divide by 8. (512Mbit / 8 = 64MByte per chip).

Segment 1: The Prefix (MT)

• 99% of Micron memory parts start with MT (Micron Technology).
• Rarely, you’ll see JS or 8C for older or fab-specific parts, but consumer decoders focus on MT.

How to decode reliably

1. Get the full Micron part number printed on the device or datasheet.
2. Refer to the specific product family datasheet or part number guide on Micron’s website — family-specific tables map each character group to meaning.
3. When in doubt, match the part number against Micron’s ordering guide or contact Micron support for exact interpretation.
