Micron Memory Part Number Decoder

Before we decode, a critical warning: Legacy parts (DDR2/DDR3) use a slightly different syntax than modern DDR4/DDR5 or LPDRAM.

For DDR5, you’ll see -40 (DDR5-4000), -48 (DDR5-4800), or -62 (DDR5-6200). micron memory part number decoder

Example: MT40A512M16LY-075E:E

| Field | Code | Meaning | |-------|------|---------| | MTA | Micron Module | | 18 | Module generation/density factor | | ADF | Module type (ADF = DDR4 RDIMM, ASF = SODIMM, etc.) | | 2G | Total module density (2GB per rank or total) | | 72 | Data width (72 bits = 64 + 8 ECC) | | AZ | PCB/configuration code | | -3G2E1 | Speed: 3G2 = DDR4-3200, E1 = specific timing/temperature | Before we decode, a critical warning: Legacy parts

: Identifies the technology, such as A for SLC (Single Level Cell). Before we decode
