Micron Memory Part Number Decoder Review

A typical Micron DRAM part number looks like this: A NAND part number example: MT29F4G08ABADAWP-IT:D

Each field matters. For instance, “WP” tells a layout engineer the exact package dimensions—48-pin TSOP I vs. 63-ball BGA. The “IT” ensures that an industrial router will not fail in a hot factory.

Micron uses a two-letter code to describe the physical packaging, lead-free status, and specific physical pinouts of the chip. Because packaging changes frequently with smaller die shrinks, referring to the specific datasheet is always recommended. Common examples include:

Some part numbers include a letter designator for the operating voltage, though this is sometimes combined into the technology field. Standard voltage (e.g., 1.2V for DDR4). U: Ultra-low voltage (e.g., 1.1V). 4. Configuration and Density micron memory part number decoder

If you have a physical chip and can't find the full part number, look for the 5-digit FBGA code (e.g., D9VRL). FBGA & Component Marking Decoder Micron’s official lookup tool to convert that 5-digit code into a full part number. Part Catalog : Once you have the full MPN, the Micron Part Catalog provides the specific datasheet for that revision. Why Does This Matter? System Compatibility

: The decoder is specifically for FBGA-packaged components. Standard modules (like DIMMs) typically use a Serial Presence-Detect (SPD) Lookup Mobile Experience

: 1 Gigabit total capacity, configured with an 8-bit wide data bus.

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 A typical Micron DRAM part number looks like

: The single letter at the very end is the die revision. It shows the version of the design. "A" is the first version, "B" is the second, and so on. 5. Speed Grade

: Get detailed timing and configuration data for a full module. 2. Standard Part Number Breakdown (DRAM)

. For overclockers, this is the most critical part. Certain revisions, like the legendary (D-die) or The “IT” ensures that an industrial router will

: Covers full DIMM/SODIMM labels, including voltage, rank, and clock speed.

: Used in DDR5 to denote specific MT/s ratings (e.g., DDR5-4800). 8. Die Revision (:E)

: Identify if it is an individual DRAM component ( MT40 ), a NAND flash chip ( MT29 ), or a full module ( MTA / MTF ).
