Micron memory part numbers can feel like trying to solve a puzzle, but once you know the "key," it's actually quite simple. Micron uses a standardized naming convention where each character in the string represents a specific technical attribute of the component. The Basic Structure

✅ Summary

• Components → MT[gen][density][org][package]-[speed]:[rev]
• Modules → MTA[gen][type][density][width][config]-[speed]
• NAND → MT29F[density][width][voltage][package]

Micron's DRAM Component Part Numbering System typically follows a standard sequence (e.g., MT40A1G8SA-075:E): Example Codes Prefix Manufacturer MT = Micron Technology Family Memory Type 40 = DDR4; 41 = DDR3; 60 = LPDDR5 Voltage Operating Volts A = 1.2V; K = 1.35V; L = 1.5V Density Storage Capacity 1G8 = 8Gb (1Gb x 8 configuration) Speed Clock/Data Rate -075 = 2666 MT/s; -062E = 3200 MT/s Revision Die Generation :E, :F, or :A (Designates the design shrink) 4. Decoding NAND Flash Components NAND Flash parts (e.g., MT29F32G08ABAAA ) focus on internal organization and bit density: FBGA and part decoder | Micron Technology Inc.

Segment 1: The Prefix (MT)

• 99% of Micron memory parts start with MT (Micron Technology).
• Rarely, you’ll see JS or 8C for older or fab-specific parts, but consumer decoders focus on MT.

1. Type (MT + generation + form factor)
2. Function (buffered, voltage, ECC)
3. Size (density and width)
4. Speed (the hyphenated suffix)

: It acts as a bridge between the physical marking on a chip (e.g., a five-digit alphanumeric string like "D9WFK") and the official Marketing Part Number (MPN) Data Sheet Access

Example decodes

• 6. The Speed Grade (-083E)

  This is critical for timing.
