Relying solely on visual inspection or operating system readouts can lead to purchasing errors. Micron utilizes two primary identifiers on its products:
While the string of characters looks cryptic at first glance, it follows a logical structure. This guide will help you decode a Micron part number (PN) to determine the density, speed, form factor, and package type without needing a datasheet.
A single letter indicates the power requirements of the silicon: Standard Voltage (e.g., 1.2V for DDR4) K: Ultra-low voltage variants
: Identify if it is an individual DRAM component ( MT40 ), a NAND flash chip ( MT29 ), or a full module ( MTA / MTF ). micron memory part number decoder
If you are currently looking at a specific Micron component and trying to decipher its specifications, I can help you break down the code. Please share the or the 5-digit FBGA code printed on your Micron device, along with the type of hardware it is installed on. Share public link
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) |
: Enter the 5-digit code found on the physical chip to get the full "MT" part number. Relying solely on visual inspection or operating system
This guide breaks down Micron’s part number numbering system so you can accurately decode any Micron memory component. Why Decoding Micron Part Numbers Matters
Indicates a slower speed grade, typically corresponding to DDR4-2666. 7. Operating Temperature Range
: It acts as a bridge between the physical marking on a chip (e.g., a five-digit alphanumeric string like "D9WFK") and the official Marketing Part Number (MPN) Data Sheet Access A single letter indicates the power requirements of
Whether you are an IT manager, an electronics hobbyist, or a motherboard designer, this decoder guide gives you the power to look at any Micron memory component and know exactly what it is.
: Refer to the DDR5 Module Part Numbering System or the Legacy DDR4/DDR3/DDR2 Guide for detailed breakdowns of speed bins and configurations.
