Micron Memory Part Number Decoder

Thus, ASF = Unbuffered, 1.2V, standard package.

Identify family → find density/organization → map speed/voltage code → read package/temp → confirm revision/assembly.

Micron's NAND Flash and Solid-State Drives use a similar alphanumeric matrix, though the variables focus heavily on storage cells and interface protocols. [MT] [FD] [DA] [K] [1T0] [TBD] - [1A] [1] [2] [AZ] [YY]

When looking at storage, pay close attention to these specific indicators within the string: micron memory part number decoder

Let us analyze a typical Micron DRAM part number example: 1. Brand Identifier (Prefix)

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 unbuffered DIMM. Plugging the wrong one into a server motherboard might prevent POST (Power-On Self-Test).

Directly following the density is the bit configuration, indicating the data bus width per component: : x4 configuration (4 bits wide) 8 : x8 configuration (8 bits wide) 16 : x16 configuration (16 bits wide) 6. Package Code (SA)

Decode:

To decode a physical chip, you must convert this 5-digit marking back into the full global part number. [MT] [FD] [DA] [K] [1T0] [TBD] - [1A]

Almost all Micron component part numbers begin with the prefix . This simply stands for Micron Technology. 2. Memory Product Type
