Following the hyphen, this code indicates the maximum speed the memory can safely achieve. Micron uses exact nanosecond ratings or megatransfers (MT/s) markers:

The Ultimate Guide to the Micron Memory Part Number Decoder In the world of high-performance computing, the string of characters etched onto a RAM chip or printed on an SSD label isn't just a serial number—it’s a dense, encoded biography of the hardware. Whether you are a system builder, an overclocker, or a curious tech enthusiast, understanding the Micron part number decoder

: For memory modules, the SPD Part Number Lookup provides Serial Presence-Detect data essential for BIOS configuration. micron memory part number decoder

Indicates the total storage capacity and data bus width.

Understanding Micron memory part numbers is essential for sourcing, replacing, or upgrading hardware. Micron uses a complex system of letters and numbers to compress detailed technical specifications into a single string. This guide breaks down the structure of Micron part numbers for both DRAM and NAND flash memory, allowing you to decode any part number manually. Structural Overview of Micron Part Numbers Following the hyphen, this code indicates the maximum

“1G16” splits into two parts: density and width. “1G” means 1 gigabit (Gb) of total memory. However, DRAM chips are often organized as “1G x 16,” where “16” indicates the device width in bits (DQ pins). A “16” yields a 16-bit-wide interface. Other common widths: 4, 8, or 32. Multiplying density by width confirms total capacity: 1Gb × 16 = 16Gb per chip? Wait—caution: In Micron’s notation, “1G16” actually means a 16-bit-wide device with a total density of 16 gigabits (because 1G refers to the number of words, and 16 bits per word). More precisely, it is 1G words × 16 bits = 16 Gb. For a designer building a 64-bit DIMM, four such chips would be needed. Indicates the total storage capacity and data bus width

The package code consists of two letters indicating the physical casing, physical dimensions, material composition (lead-free vs. leaded), and ball grid array (BGA) layout. Because these change frequently across generations, consulting Micron's active packaging catalog is essential. Common examples include: : 78-ball FBGA (DDR4) VA : 96-ball FBGA (DDR4) HC : 78-ball FBGA (DDR5) 5. Speed Grades and Cycle Times
