Because Micron produces thousands of variations, they use a structured, alphanumeric part numbering system. This guide acts as a to help you understand exactly what lies beneath the part number (MPN). 1. Why Decode Micron Part Numbers?

Micron offers supplemental guides for specific product categories: FBGA and part decoder | Micron Technology Inc. micron memory part number decoder

Before we decode, a critical warning: Legacy parts (DDR2/DDR3) use a slightly different syntax than modern DDR4/DDR5 or LPDRAM.

: Identify if it is an individual DRAM component ( MT40 ), a NAND flash chip ( MT29 ), or a full module ( MTA / MTF ). : Get detailed timing and configuration data for

Most Micron DRAM part numbers follow this pattern: . Common Codes Definition Technology 40 (DDR4), 60 (DDR5), 41 (DDR3) The generation of memory. Configuration 1G8 (8Gb x8), 512M16 (8Gb x16) Depth (density) and data bus width. Voltage A (1.2V), B (1.1V), K (1.35V) Operating voltage requirements. Speed Grade -062E (DDR4-3200), -075 (DDR4-2666) Max frequency and timing (CL-tRCD-tRP). Die Revision :E , :B , :A The specific manufacturing "generation" or "die". 3.

“-062E” is where timing enthusiasts focus. The “062” indicates the minimum cycle time in nanoseconds (ns)—here, 0.62 ns, which corresponds to a data rate of 1600 MHz (DDR4-3200). For older parts, “-125” meant 1.25 ns = DDR-800. The trailing “E” specifies the CL (CAS latency) and timing table, e.g., CL22 for DDR4-3200. Speed grade mismatches can cause system instability or failure to boot. This guide acts as a to help you

Understanding a Micron memory part number is essential for identifying the exact specifications of RAM or SSD components. Because physical space on a chip is limited, Micron uses shorthand "FBGA codes" (often starting with ) that require an official decoder to translate into a full part number. Using the Official Decoder Tools

: 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).

The Micron Memory Part Number Decoder is an intuitive and user-friendly tool that can be accessed through Micron's website. Once you enter the part number, the decoder provides a breakdown of the part number, including:
