For DDR5, you’ll see -40 (DDR5-4000), -48 (DDR5-4800), or -62 (DDR5-6200).
If you need help identifying a specific component, please share the or the 5-digit FBGA code printed on your chip. I can also break down the precise pin layout or timing latencies for a particular memory generation if needed. Share public link
Understanding Micron memory components often requires navigating a complex system of alphanumeric codes. Because physical space on high-density chips is limited, Micron uses two primary methods for identification: full and abbreviated FBGA Codes (often called "D9 codes"). 1. What is the Micron FBGA Part Marking 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) micron memory part number decoder
Micron’s NAND Flash uses a slightly different prefix and structure (e.g., ): MT29F : Standard Single-Supply NAND Flash. Density : Indicated by codes like 1G, 8G, or 128G.
As technology advances, DDR5 module part numbers have updated to reflect higher speeds and new power management features. MT : Micron C : DDR5 SDRAM 40 : Density (e.g., 40 = 16Gb/32Gb) F : Voltage/Die Revision S1 : Speed (e.g., 48B = DDR5-4800B) C : Module Type (e.g., C = SODIMM) 5. Summary Table for Quick Reference Code Examples Description Product 40/41/42/53 DDR4/DDR3/LPDDR2/LPDDR4 Voltage 1.2V / 1.35V / 1.8V / 1.0V Speed -25 / -187E / -093E Higher number = slower cycle time Temp IT / AT / (Blank) Industrial / Automotive / Commercial Revision :A / :B / :C Indicates die revision level
: Use the SSD Part Numbering System to identify drive interfaces and NAND types. For DDR5, you’ll see -40 (DDR5-4000), -48 (DDR5-4800),
Let’s break down the Micron memory part numbering system.
Here is how we dissect this string character by character.
Micron provides a suite of resources beyond just the part number decoder to support your design and selection process: What is the Micron FBGA Part Marking Decoder
MT [Version] [Type] [Density/Cap] [Org] [Package] [Speed] [Special Features]
Indicates a specific FBGA package dimension used in DDR4. SA: Common package code for specific monolithic layouts. 6. Speed Grade / Cycle Time
A two-letter code specifies the physical package, ball count, and material composition (such as lead-free or halogen-free matrices).
NOR Flash part numbers, such as the popular MT25QL128ABA1ESE-0SIT in the MT25Q series or the legacy M25P and N25Q series, follow their own structure for easy identification . For the series, the part number N25Q064A11E reveals:
This is the most critical number for performance compatibility. Micron uses a specific digit to represent the transfer rate in MT/s (MegaTransfers per second).
