Micron Memory Part Number Decoder

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

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:

Micron memory part numbers can feel like trying to solve a puzzle, but once you know the "key," it's actually quite simple. Micron uses a standardized naming convention where each character in the string represents a specific technical attribute of the component. The Basic Structure

A typical Micron part number (MPN) usually follows this flow:

[Brand] [Technology] [Voltage] [Density] [Configuration] [Package] [Speed] [Revision] How to Decode the Key Segments Brand Identifier : Usually starts with (Micron Technology). Technology Type : DDR4 SDRAM : DDR5 SDRAM : Graphics Memory (GDDR) : NAND Flash Operating Voltage : 1.35V (Low Voltage) : This indicates the total capacity (e.g., for 4 Gigabits, The Ultimate Guide to the Micron Memory Part

for 16 Gigabits). Remember, this is often in bits, not bytes! Configuration : Tells you the data bus width (e.g., x4, x8, or x16 Speed Grade : Look for the suffix after the package code (e.g., for DDR4-3200). Pro Tools for Quick Decoding

If you have a physical chip and can't find the full part number, look for the 5-digit FBGA code (e.g., D9VRL).

Decoding the DRAM Part Number Structure

Let us dissect the DRAM example: MT40A1G16RC-062E:B

1. Prefix – The Manufacturer Identifier
The initial “MT” is the universal prefix for Micron Technology. This distinguishes Micron parts from those of Samsung (K4…), SK Hynix (H5…), or other vendors.

2. Product Family and Voltage
The next characters define the DRAM generation and voltage. In “40A,” the “40” indicates DDR4 SDRAM. (For DDR3, this would be “41” or “8K”; for DDR5, newer prefixes like “60B” appear). The “A” denotes the specific version or design family, often linked to voltage—for example, “A” typically signifies 1.2V VDD/VDDQ for DDR4. This field is critical because mixing voltages can destroy components.

3. Density and Organization
“1G16” splits into two parts: density and width. “1G” means 1 gigabit (Gb) of total memory. However, DRAM chips are often organized as “1G x 16,” where “16” indicates the device width in bits (DQ pins). A “16” yields a 16-bit-wide interface. Other common widths: 4, 8, or 32. Multiplying density by width confirms total capacity: 1Gb × 16 = 16Gb per chip? Wait—caution: In Micron’s notation, “1G16” actually means a 16-bit-wide device with a total density of 16 gigabits (because 1G refers to the number of words, and 16 bits per word). More precisely, it is 1G words × 16 bits = 16 Gb. For a designer building a 64-bit DIMM, four such chips would be needed.

4. Package and Ball Configuration
“RC” is a package designator. “R” often stands for a 78-ball BGA (for x16 DDR4), while “C” may specify the ball map or lead-free status. Other letters indicate different ball counts or package types (e.g., “U” for 96-ball BGA). This field ensures physical compatibility with PCB footprints.

5. Speed Grade (The Performance Key)
“-062E” is where timing enthusiasts focus. The “062” indicates the minimum cycle time in nanoseconds (ns)—here, 0.62 ns, which corresponds to a data rate of 1600 MHz (DDR4-3200). For older parts, “-125” meant 1.25 ns = DDR-800. The trailing “E” specifies the CL (CAS latency) and timing table, e.g., CL22 for DDR4-3200. Speed grade mismatches can cause system instability or failure to boot.

6. Revision and Special Flags
The colon and “B” denote the die revision. This is crucial for tracking errata, power changes, or timing improvements. Revision letters are sequential (A, B, C…). Sometimes an “IT” appears before the revision, signifying Industrial Temperature range (-40°C to +95°C) instead of Commercial (0°C to +95°C). An “A” at the end might indicate automotive grade.

Decoding Discrete DRAM Chips (Components)

If you have a bare Micron DRAM chip (like MT40A1G16RC-083E), the decoder differs slightly.

Example: MT40A1G16RC-083E

  • MT40 = Base DRAM component family (DDR4)
  • A = Generation / voltage (1.2V)
  • 1G = 1 Gigabit per chip
  • 16 = Organization (x16, meaning 16 I/O pins)
  • RC = Package type (78-ball FBGA)
  • 083E = Speed (DDR4-2400, 083 = 0.833ns cycle time)
  • E = Halogen-free / lead-free

Why You Need to Decode Micron Part Numbers

Before diving into the syntax, understand the stakes. Two memory modules can look identical physically but have entirely different electrical characteristics. For example, a Micron module labeled MTA18ADF2G72AZ is a 16GB DDR4 ECC registered DIMM. Change one character—MTA18ASF2G72AZ—and it becomes a non-ECC unbuffered DIMM. Plugging the wrong one into a server motherboard might prevent POST (Power-On Self-Test).

Common use cases for the decoder:

  • Verifying OEM parts before buying surplus memory.
  • Cross-referencing a damaged module’s replacement.
  • Designing embedded systems where exact timings and voltages matter.
  • Upgrading laptops soldered with Micron DRAM packages.

1. Micron DRAM Part Number Decoder (DDR4 / DDR5)

This is the most common format used for SDRAM components. The part number usually follows a 13- to 15-character alphanumeric string.
