NOR Flash part numbers, such as the popular MT25QL128ABA1ESE-0SIT in the MT25Q series or the legacy M25P and N25Q series, follow their own structure for easy identification . For the series, the part number N25Q064A11E reveals:
While each product family (DDR4, DDR5, NAND) has its own specific logic, most follow a standardized structure: 1. The Core Prefix: MT Every Micron part begins with , which stands for "Micron Technology". 2. Product Family The numbers following "MT" identify the technology type: DDR4 SDRAM DDR3 SDRAM DDR5 SDRAM (Current generation) NAND Flash Solid State Drive (SSD) 3. Configuration and Density
If you are currently trying to decode a specific string, tell me: The or 5-digit FBGA code The device it came from (e.g., server, laptop, custom PCB) micron memory part number decoder
Micron memory part numbers encode device family, density, organization, package, speed, voltage, temperature, and optional features. Use this quick reference to decode typical Micron DRAM and NAND part numbers.
Below is a detailed decoder guide broken down by product family. NOR Flash part numbers, such as the popular
: The decoder is specifically for FBGA-packaged components. Standard modules (like DIMMs) typically use a Serial Presence-Detect (SPD) Lookup Mobile Experience
Modern DDR4 parts, like the MT40A512M16LY-083R or MT40A1G16WBU-083E , have evolved to include details like density (512M or 1G depth), data width (x16), and specific speed ratings like 083E . Use this quick reference to decode typical Micron
MT41K256M16HA‑125:
For the most accurate and up-to-date hardware design decisions, always cross-reference your decoded values with Micron’s official active component datasheets.
Micron solves this by using a special FBGA Code. This is a short, five-character code printed on the component's top marking. If you search the internet for this code, you likely won't find anything, as it is not the part number.
