Micron Memory Part Number Decoder __hot__ -

If your chip says something like or NW912 , you cannot look up data sheets using that code directly. You must convert it back to the global part number. Navigate to the official Micron website. Locate their online FBGA Device Marking Decoder tool. Enter the 5-digit code printed on the physical chip.

Most Micron memory chips don't have the full part number printed on them. Instead, they use a 5-digit FBGA code.

In our example, indicates a x8 data width . Combined with the density, this chip is organized as 128 Meg x 8. 5. Package and Hardware Attributes

Following the hyphen is the speed rating. This dictates the maximum clock frequency or data transfer rate. 0.75ns cycle time (Equivalent to DDR4-2666) -062E: 0.625ns cycle time (Equivalent to DDR4-3200) -083: 0.833ns cycle time (Equivalent to DDR4-2400) Our example -075 decodes to a DDR4-2666 speed rating . 7.

Notes:

Micron provides official part numbering guides as downloadable PDFs and XLSX files for detailed decoding. The "DRAM Component Part Numbering System" covers DDR4, DDR3, DDR2, DDR, SDRAM, mobile LPDDR, RLDRAM, and GDDR memory. For legacy DDR3/L, DDR2, and older technologies, a specific legacy part numbering system is available. Similarly, the "Micron Module Part Numbering Guide" is the official resource for decoding DDR5, DDR4, and DDR3 modules.

Micron memory chips often do not display their full part numbers directly on the chip. Space constraints on compact FBGA (Fine-Pitch Ball Grid Array) packages mean only an abbreviated marking is printed on each component, which is completely different from the official part number. A typical Micron chip might show markings like “PPE39 7LW75 D9WDL” where only the second or third line of text is the identifying code. This is where a decoder is essential.

This section defines how much memory is on the chip and how the data lanes are organized. It is usually broken down into a total density prefix followed by the configuration bit-width (
