Micron Memory Part Number Decoder -

Micron structures its part numbers into distinct logical blocks. While the exact meaning of each position shifts slightly between DRAM, LPDDR, and NAND, the fundamental blueprint remains consistent.

If you have a specific code you are trying to read, tell me the or the 5-digit chip marking , and I will break down its precise specifications for you. Share public link

: Ensure you are reading the printed part number on the chip surface, not the tracking lot code or date code (which are usually shorter and change per batch).

| Field | Code | Meaning | |-------|------|---------| | MTA | Micron Module | | 18 | Module generation/density factor | | ADF | Module type (ADF = DDR4 RDIMM, ASF = SODIMM, etc.) | | 2G | Total module density (2GB per rank or total) | | 72 | Data width (72 bits = 64 + 8 ECC) | | AZ | PCB/configuration code | | -3G2E1 | Speed: 3G2 = DDR4-3200, E1 = specific timing/temperature |

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

Apply the appropriate product-line-specific table or Micron datasheet mapping for exact meanings.

Due to space constraints on tiny integrated circuits (ICs), Micron prints a short five-digit code (e.g., D9VPP ) on individual chips. Micron structures its part numbers into distinct logical

Micron Technology utilizes a sophisticated alphanumeric coding system to specify the architecture, performance, and physical characteristics of its semiconductor products. These part numbers serve as a compact data sheet, allowing engineers and procurement specialists to identify specific memory technologies without full documentation. 2. The Relationship Between Markings and Part Numbers

Once you have that 5-digit code, you can get the full part number (which usually starts with ) using Micron's official tool: Micron FBGA Part Marking Decoder

Micron DRAM part numbers follow a strict, standardized nomenclature. While exact layouts can vary slightly between generations (DDR3, DDR4, DDR5, and LPDDR), a standard Micron commercial DRAM part number generally breaks down into the following fields:

For example, an SSD part number like decodes to a Micron NVMe SSD ( MTF ), using a specific controller generation ( DKBA ), with a 1TB capacity ( 1T0 ). Steps to Decode Any Micron Part Number Share public link : Ensure you are reading

Micron provides a on their support site (Micron.com → Support → Part Number Decoder). However, it doesn’t always cover discontinued parts. This guide helps you decode those legacy modules manually.
