Learning to decode Micron’s part numbers saves you from costly compatibility errors and helps you source exact replacements in seconds. While the system looks intimidating at first glance, it follows strict JEDEC and internal logic. Memorize the core segments:
[Brand] [Technology] [Voltage] [Density] [Configuration] [Package] [Speed] [Revision] How to Decode the Key Segments Brand Identifier : Usually starts with (Micron Technology). Technology Type : DDR4 SDRAM : DDR5 SDRAM : Graphics Memory (GDDR) : NAND Flash Operating Voltage : 1.35V (Low Voltage) : This indicates the total capacity (e.g., for 4 Gigabits,

Micron uses different prefixes and numerical blocks for different product categories: FBGA and part decoder | Micron Technology Inc.
| Code | DDR Generation | Speed (MT/s) | CAS Latency | |------|----------------|--------------|---------------| | -062E | DDR4 | 3200 | CL22 | | -075E | DDR4 | 2666 | CL19 | | -083E | DDR4 | 2400 | CL17 | | -093E | DDR4 | 2133 | CL15 | | -062F | DDR5 | 4800 | CL40 | | -046F | DDR5 | 5600 | CL46 |
A standard Micron part number follows a specific hierarchy. For instance, in a DDR4 or DDR5 component, the segments typically represent: Manufacturer (MT = Micron Technology) micron memory part number decoder
: Indicates 128 Gigabits or 512 Gigabits organized in a x8 configuration. Cell Type Technology : A : SLC (Single-Level Cell - High endurance) B : MLC (Multi-Level Cell) C : TLC (Triple-Level Cell - Standard consumer grade) D : QLC (Quad-Level Cell - High density) Operating Voltage : C : 3.3V Vcc, 1.8V VccQ E : 1.8V Vcc, 1.8V VccQ Form Factor Modules (SSDs and RAM Sticks)
Voltage (e.g., A = 1.2V VDD, B = 1.1V VDD, K = 1.35V VDD) 128M16: Configuration (Density and Width: 128M × 16 bits) D1: Technology Mark
Micron memory part numbers can feel like trying to solve a puzzle, but once you know the "key," it's actually quite simple. Micron uses a standardized naming convention where each character in the string represents a specific technical attribute of the component. The Basic Structure Learning to decode Micron’s part numbers saves you
This article serves as a complete —breaking down every segment of the code for DRAM modules, discrete DRAM components, and solid-state drives.
This section defines the basic technology type of the memory device. DDR4 SDRAM 60: DDR5 SDRAM 41: Low-Power DDR4 (LPDDR4) 62: Low-Power DDR5 (LPDDR5) 29F: NAND Flash Memory 3. Operating Voltage and Configuration
The initial “MT” is the universal prefix for Micron Technology. This distinguishes Micron parts from those of Samsung (K4…), SK Hynix (H5…), or other vendors. Technology Type : DDR4 SDRAM : DDR5 SDRAM
