Micron Memory Part Number Decoder -
These two letters tell you the physical form factor, ball grid array (BGA) layout, and whether the component uses lead-free materials. 78-ball FBGA (DDR4) SA: 78-ball FBGA (DDR4, specific dimensions) GE: 96-ball FBGA (DDR4) HC: 78-ball FBGA (DDR5) 5. Speed Grade and Timings
Micron DRAM components (DDR4, DDR5, LPDDR) generally follow a consistent structure. Let's break down a common example: Decoding MT40A1G8SA-062E IT:E
Usually printed in a format like D9XVK or D9ZLN .
Thus, ASF = Unbuffered, 1.2V, standard package.
If you see -40 anywhere in the suffix, that usually indicates -40°C operating range. Standard parts will not have that. For embedded systems, never substitute a commercial part for an industrial one. micron memory part number decoder
Locate the 5-digit code printed on the top surface of the IC (Integrated Circuit). It usually starts with a letter like "D9" for DRAM or "NW" for NAND.
Understanding Micron Memory Part Numbers: The Ultimate Decoder Guide
For the latest parts (DDR5, LPDDR5X, CXL memory modules), the same principles apply—only the speed codes and voltage letters will evolve. Bookmark this article and come back whenever you encounter a mysterious string of characters on a stick of RAM.
On smaller memory chips, there is not enough physical surface area to print the full 12 to 18-character part number. To solve this, Micron prints a , known as the FBGA code . These two letters tell you the physical form
MT40A1G16RC-083E
Using the Micron Memory Part Number Decoder is straightforward:
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.
After the product family comes the capacity and width. For example, indicates a density of 512 Megabits with a 16-bit wide bus. 4. Speed Bins and Latency The segment after the hyphen (e.g., ) tells you the performance rating. Refers to DDR4-2400 (1200 MHz). Common in DDR5, indicating specific JEDEC speed bins. 5. Die Revision (The "Binning" Secret) The letter at the very end (e.g., Die Revision Let's break down a common example: Decoding MT40A1G8SA-062E
: The full tracking string used for ordering and datasheets (e.g., MT40A2G8AG-062E:B ).
Micron uses two distinct identification systems that often confuse users: Marketing Part Number (MPN): The full identifier (e.g., MT40A512M16LY-083R:H ). These are found on module labels and invoices. FBGA Code: A short, 5-digit alphanumeric code (e.g.,
Identifies the number of stacked dies inside a single package container. Package Type: B: WPTSOP H1 (Lead-free) C: VBGA (Lead-free)
