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]

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.
3. 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)
4. 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)

🧠 DDR Module Decoder (e.g., MTA18ADF2G72AZ-3G2E1)

Micron modules (DIMMs, SODIMMs, RDIMMs) use a different format.

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.

LPDDR/DDR5 differences

• LPDDR uses different family codes and often includes IO voltage and low-power characteristics explicitly.
• DDR5 part numbers encode additional features (on-die ECC, PMIC presence) — expect longer suffixes and different letters.

The Golden Rule: Datasheet First

Before we decode, a critical warning: Micron has changed its numbering scheme over time. Legacy parts (DDR2/DDR3) use a slightly different syntax than modern DDR4/DDR5 or LPDRAM.

Always cross-reference your decoded guess with the official Micron datasheet. That said, the standard configuration follows a reliable pattern.

2. Micron NAND Flash Part Number Decoder

NAND Flash part numbers are distinct and often longer, typically starting with MT29 or MT followed by 'F'.

Format: MT Type Family Density Device Block Voltage Package Temp

Segment 3: Module Type Code (18 or 16)

This two-digit or three-digit code describes the form factor and function: | Code | Meaning | |------|---------| | 8 | 72-pin SIMM (obsolete) | | 16 | 168-pin DIMM (SDRAM) | | 18 | Standard DIMM (DDR1 through DDR5) | | 20 | SODIMM (Small Outline DIMM) for laptops | | 26 | Mini-RDIMM | | 32 | MicroDIMM | | 36 | CUDIMM (for DDR5 with clock driver) |

In MTA18ASF..., the 18 means it is a standard 288-pin DIMM (desktop/server form factor).

4. Speed Grade (-2E3)

This is the most critical number for performance compatibility. Micron uses a specific digit to represent the transfer rate in MT/s (MegaTransfers per second). MTA : This prefix indicates that the part

• - (Separator)
• 2: The speed multiplier. In DDR4, the number represents the "hundreds" place of the MT/s.
  • 2 = 2400 MT/s (DDR4-2400 / PC4-19200)
  • 2E = 2666 MT/s (DDR4-2666 / PC4-21300)
  • 3 = 3200 MT/s (DDR4-3200 / PC4-25600)
• E: Often indicates the specific timing bin or CL (CAS Latency) variation.
• 3: Check digit or revision iteration.
