Micron Memory Part Number Decoder ❲Plus • 2024❳
Micron DRAM part numbers (e.g., MT40A1G8SA-075:E ) follow a specific hierarchical nomenclature: Prefix/Code Manufacturer Prefix Micron Technology Product Family Identifies the technology generation 40 = DDR4; 41 = DDR3; 60 = DDR5 Voltage Operating voltage of the die A = 1.2V; K = 1.35V; L = 1.2V Density/Width Memory capacity and bus width 1G8 = 1Gb depth x 8-bit width; 256M16 = 256Mb x 16-bit Speed Grade Performance rating -075 = 2666 MT/s; -062E = 3200 MT/s Die Revision Post-colon letter indicating the silicon "step"
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
Micron memory part numbers are a unique identifier assigned to each memory module produced by the company. These part numbers contain a wealth of information about the memory module, including its type, capacity, speed, and features. A typical Micron memory part number consists of a combination of letters and numbers that can be broken down into several sections.
Separated by a hyphen, this code dictates the maximum data rate or clock frequency the chip can safely handle. DDR4-3200 (PC4-25600) with CL22 latency. -075: DDR4-2666 (PC4-21333) with CL19 latency. -48BA: DDR5-4800 with standard JEDEC timings. -56BC: DDR5-5600 with optimized latencies. 6.

These letters define the physical layout, casing, and ball count of the chip.
Thus, ASF = Unbuffered, 1.2V, standard package.

A short identifier (e.g., D9WDL ) found on the component.
: To find total module capacity: (density per chip × number of chips) / 8. But the easier way: look at the number before the letter G . 2G72 is a 16GB module when using modern DDR4 (2G x 72 bits = 16GB). Actually, let's correct: 2G = 2G Bytes? No — in Micron’s lexicon, 2G72 means the module uses 2Gb chips x 72 = 144Gb total / 8 = 18GB? This is confusing.
Micron provides a suite of resources beyond just the part number decoder to support your design and selection process: These part numbers contain a wealth of information
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.
-083E is faster than -093E because the number represents nanoseconds (lower = faster). For DDR4, -075 = 2666 MT/s (0.75ns cycle), -083 = 2400 MT/s.
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.
