Indicates the data bus width. means an x8 bus width, which is the standard for most modern NAND flash interfaces. 4. Cell Type / Architecture (C)
Directly following "MT" are the characters indicating the specific class of memory. : DDR4 SDRAM 60B : DDR5 SDRAM 41K : DDR3L SDRAM (Low Voltage 1.35V) 46V : DDR1 SDRAM 47H : DDR2 SDRAM 53D : LPDDR4 / LPDDR4X Mobile RAM 62M : LPDDR5 Mobile RAM 3. Configuration and Density
This paper outlines the technical framework and methodology for decoding Micron Technology's memory part numbering systems. Technical Analysis: Micron Memory Part Number Decoding 1. Introduction to Micron Part Numbering
By mastering these codes, you eliminate the guesswork from hardware maintenance and upgrades. micron memory part number decoder
: Marks the die generation or manufacturing stepping. 💾 Section 1: Decoding Micron DRAM Part Numbers
The it came out of (like a PC, laptop, or video card) I can look up the exact specs, speed, and size for you. Share public link
When looking at storage, pay close attention to these specific indicators within the string: Indicates the data bus width
for 16 Gigabits). Remember, this is often in bits, not bytes! Configuration : Tells you the data bus width (e.g., x4, x8, or x16 Speed Grade : Look for the suffix after the package code (e.g., for DDR4-3200). Pro Tools for Quick Decoding
: Compare Micron parts with competitors by entering at least five characters of a part number. 2. Part Numbering Guides (PDFs)
Specifies the core technology family (e.g., DDR4, DDR5, LPDDR4). Cell Type / Architecture (C) Directly following "MT"
Notes:
This segment defines the fundamental memory technology. It tells you whether you are dealing with standard desktop/server RAM, low-power mobile RAM, or legacy graphics memory. : DDR2 SDRAM MT41K / MT41J : DDR3L (1.35V) / DDR3 (1.5V) SDRAM MT40A : DDR4 SDRAM MT60B : DDR5 SDRAM MT52L / MT53E : LPDDR3 / LPDDR4X / LPDDR5 (Low Power Mobile) 3. Density and Configuration
If you look directly at a physical Micron RAM chip, you will rarely see the full part number printed on it. Because memory chips are physically small, Micron prints a short known as the FBGA Part Marking (or "FBGA Code"). How to use the FBGA Code:
