Memory Part Number Decoder _top_ — Micron

: Memory chips are very small. The long standard part number cannot fit on the tiny plastic case. Micron prints a short five-digit code on the chip instead. This short text is called an FBGA code.

Misidentifying memory components leads to costly design errors, system incompatibilities, and supply chain delays. By mastering the Micron decoder, you can: Verify exact hardware specifications before purchasing. Find precise, drop-in replacements for obsolete parts. micron memory part number decoder

MT40A512M16LY-075E:E → DDR4 family; 512M x16 (8Gb die); LY = package/IO; -075 = speed grade (~DDR4-2400–2666 class); E = commercial; final :E = revision. : Memory chips are very small

Separated by a colon, the final letter represents the generation of the silicon die: First generation of that specific density architecture. This short text is called an FBGA code
