“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.
A standard Micron part number follows a specific hierarchy. For instance, in a DDR4 or DDR5 component, the segments typically represent: Manufacturer (MT = Micron Technology) micron memory part number decoder
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 “1G16” splits into two parts: density and width
: Details for drive interface (SATA/PCIe), form factor, and sector size. 3. Common DRAM Prefix Examples FBGA and part decoder | Micron Technology Inc. A “16” yields a 16-bit-wide interface
So 2G72 in our example = .
: Decodes prefixes like MT40A (DDR4) or MT60B (DDR5) and suffix details for density, configuration, and speed.
