Micron Memory Part Number Decoder [verified] Jun 2026

The fastest way to decode a Micron part is through their official web utilities:

A typical component part number (e.g., ) follows this general template: Prefix MT Micron Technology. Product Family 40 Technology type (40=DDR4, 62=LPDDR5, 41=DDR3). Voltage A Operating voltage (A=1.2V, F=1.1V for LPDDR5). Configuration 1G8 Density and width (e.g., 1 Gig x 8). Package Code SA Physical package type and lead-free status. Speed Grade -062E Maximum clock frequency or data rate. Temp / Status IT Operating environment (IT=Industrial, AT=Automotive). Die Revision :E The design version of the silicon. DDR5 Module Part Numbering System - Micron Technology 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. The fastest way to decode a Micron part

Notes:

This is the per-chip density, not the module size. Configuration 1G8 Density and width (e

: Commonly found on the bottom line of text on a chip, these 5-character codes (e.g., D9WFL) are essential for finding the actual part number.
