Micron Memory Part Number Decoder _verified_ Jun 2026
Micron makes memory chips for computers, phones, and servers. Each chip has a long string of letters and numbers printed on it. This text is called a part number.
Micron DRAM component part numbers typically look like this: .
NAND Flash part numbers differ slightly to accommodate flash-specific features. Example: MT: Micron 29F: NAND Flash Family 4G: Density ( 08: Bus Width ( ×8cross 8 A: Operating Voltage B/ADA/WP: Features, Generation, Package IT: Industrial Temperature :D: Die revision 4. Micron FBGA Part Marking Decoder (Short Code)
On many small memory chips, there is not enough physical surface area to print a full 18-character part number. To solve this, Micron prints a known as the FBGA Code (or Component Marking). How to Convert an FBGA Code to a Part Number
A single letter indicates the power requirements of the silicon: Standard Voltage (e.g., 1.2V for DDR4) K: Ultra-low voltage variants micron memory part number decoder
The characters following the hyphen dictate the maximum operating speed or latency.
MT | 40A | 1G8 | SA | -062E | A | A | :E | TR -- --- --- -- ----- - - -- -- 1 2 3 4 5 6 7 8 9 (e.g., MT = Micron Technology) Product Family / Component Type (e.g., 40A = DDR4 SDRAM) Configuration / Density (e.g., 1G8 = 1 Gigabit x 8 bits)
Micron part numbers are hierarchical: a prefix identifies the product family, followed by blocks encoding density/organization, speed/voltage, package, temperature, and internal revision/lot codes. Notation varies across product lines (DRAM: DDR4/DDR5, LPDDR; NAND: SLC/MLC/TLC/QLC), but common motifs appear:
For a Micron NAND Flash part number like , the structure is different and tends to be more directly descriptive: Micron makes memory chips for computers, phones, and servers
: Optimized FBGA package for standard desktop/server configurations.
Use Micron’s official online "FBGA and Component Part Number Search" tool. Enter the short code to retrieve the full, standard part number, which you can then decode using the steps below. Standard Breakdown of a Micron Part Number
This is often the most critical section for engineers and buyers. It tells you the total storage capacity of the die and how the data bus is width-configured. It uses an embedded multiplier format:
A standard Micron DRAM part number generally breaks down into these nine segments: Micron DRAM component part numbers typically look like this:
The speed grade determines the maximum clock frequency and data rate the memory can safely handle. : DDR4-3200 (PC4-25600) with CL22 timing -053E : DDR4-3733 -48B : DDR5-4800 -56B : DDR5-5600 6. Die Revision
: Standard DDR4 / DDR5 voltage (e.g., 1.2V for DDR4, 1.1V for DDR5). L : Low voltage variants (e.g., 1.35V for DDR3L). 4. Density/Capacity (1G)
If you work in IT procurement, system building, or hardware repair, you have likely stared at a string of alphanumeric characters on a RAM stick and wondered what it all means. Micron Technology—parent company of the consumer-facing brand Crucial—is one of the world’s largest manufacturers of DRAM, NAND, and SSD storage. Their part numbering system is complex but incredibly logical.
Standard voltage for that specific technology generation (e.g., 1.2V for DDR4).
