Micron Memory Part Number Decoder <Newest ✭>

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 Family: This segment identifies the product family, such as:
- MT (DRAM)
- MX (Flash)
- MR (SRAM)
- MD (DRAM modules)
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.
Density: This segment represents the memory density, usually in megabits (Mb) or megabytes (MB). For example:
- 128M (128 megabits)
- 512M (512 megabits)
- 1G (1 gigabit)
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:
- Frequency (e.g., 133MHz)
- Latency (e.g., CAS 3-4-4-4)
Package: This segment describes the product's packaging, including:
- Package type (e.g., TSOP, BGA, FBGA)
- Package size (e.g., 48-ball, 64-ball)
Temperature: This segment indicates the product's operating temperature range:
- Commercial (0°C to 70°C)
- Industrial (-40°C to 85°C)
- Automotive (-40°C to 125°C)
Other Options: This segment may include additional information, such as:
- Power supply voltage (e.g., 2.5V, 1.8V)
- Data width (e.g., x8, x16, x32)

Decoding Micron DRAM Part Numbers

Let's examine a few examples of Micron DRAM part numbers:

MT41K512M16HA-125: This part number can be decoded as follows:
- MT (Product Family: DRAM)
- 41K (Product Type: DDR3)
- 512M (Density: 512 megabits)
- 16 (Data width: x16)
- HA (Package: 96-ball FBGA)
- -125 (Speed: 125MHz, CAS 7-7-7-7)
MT48LC16M16A2-75: This part number can be decoded as follows:
- MT (Product Family: DRAM)
- 48L (Product Type: SDRAM)
- C16M (Density: 16 megabits)
- 16 (Data width: x16)
- A2 (Package: 54-pin TSOP)
- -75 (Speed: 75ns)

Decoding Micron Flash Part Numbers

Now, let's examine a few examples of Micron Flash part numbers:

MX25L3205D-TI: This part number can be decoded as follows:
- MX (Product Family: Flash)
- 25L (Product Type: NOR Flash)
- 3205 (Density: 32 megabits)
- D (Data width: x1)
- TI (Package: 8-pin SOIC)
MT29F2G08AADWP: This part number can be decoded as follows:
- MT (Product Family: Flash)
- 29F (Product Type: NAND Flash)
- 2G (Density: 2 gigabits)
- 08 (Data width: x8)
- AADWP (Package: 48-pin TSOP)

Conclusion

Decoding Micron memory part numbers requires an understanding of the standardized format and the specific information conveyed by each segment. By analyzing the part number, engineers, procurement specialists, and distributors can quickly identify the product family, type, density, speed, package, and other key characteristics. This knowledge can help streamline the component sourcing process, reduce errors, and ensure compatibility with specific applications.

How to decode reliably

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

Example decoded part (concise)

MT40A512M16LY-075E:E → DDR4 family; 512M x16 (8Gb die); LY = package/IO; -075 = speed grade (~DDR4-2400–2666 class); E = commercial; final :E = revision.

NAND flash examples

Example: MT29F4G08ABAEAWP-IT
- MT29 = Micron NAND family
- F4G08 = 4Gbit, x8 organization
- ABAEAWP = process, page/erase/architecture, and package codes
- -IT = industrial temperature grade

Notes:

NAND part numbers include process node or architecture hints (SLC/MLC/TLC/QLC), die capacity, and package details (e.g., BGA vs TSOP).
ECC, page size (2K/4K), and interface (ONFI, toggle) are sometimes embedded or require cross-reference.
