Micron updates its part-numbering charts continuously. Once you have the full part number, download the exact datasheet for that family (e.g., "Micron DDR4 SDRAM Part Numbering Chart") to decode the exact package dimensions and timing constraints.
: C9 codes are often used for modules sold under the Crucial brand. 3. Decoding Framework for DRAM Components
The letters near the end show the physical shape of the chip and its design version.

| Segment (within MT29F1G08ABBHC-ET ) | Field Description | | :--- | :--- | | | Manufacturer: Stands for Micron Technology. | | 29F | Technology/Family: This block indicates the memory technology, such as 29F for NAND Flash or 29E for Enterprise NAND Flash. | | 1G | Density: This is the total memory density. 1G means 1 Gigabit (Gb) of storage. | | 08 | Device Width: The 08 specifies an 8-bit I/O width. | | A | Die & Classification: Letters like A or B can denote the number of die in the package, the number of chip enables (CE), and other architectural features. | | BB | Operating Voltage: Letters such as AB or BB are used to specify the device's core and I/O supply voltages. For instance, BB may indicate 1.8V operation. | | HC | Package: This two-character code identifies the package type, such as HC for a 63-ball VFBGA. | | -ET | Temperature & Options: The suffix often designates the operating temperature range (e.g., -ET for Extended Temperature) and other features like internal ECC. |
Micron DRAM components (DDR4, DDR5, LPDDR) generally follow a consistent structure. Let's break down a common example: Decoding MT40A1G8SA-062E IT:E
Product Family (e.g., 42 = Mobile LPDDR2, 40 = DDR4, 41 = DDR3) Micron updates its part-numbering charts continuously
Our example ends in , meaning it uses Micron's E-die architecture . Decoding Micron NAND Flash Part Numbers
The final letter tracking the physical design iteration of the flash media. The FBGA Code System (The 5-Digit Matrix)
If you are looking at a physical chip, you will likely see a 5-digit alphanumeric code (e.g., "D9VPP") rather than a full part number. FBGA and part decoder | Micron Technology Inc
Second generation (often a die-shrink, offering better efficiency). :E: Mature, highly optimized silicon revision. Field-by-Field Breakdown for Flash and NAND
Let us analyze a typical Micron DRAM part number example: 1. Brand Identifier (Prefix)
Most Micron DRAM part numbers follow this pattern: . Common Codes Definition Technology 40 (DDR4), 60 (DDR5), 41 (DDR3) The generation of memory. Configuration 1G8 (8Gb x8), 512M16 (8Gb x16) Depth (density) and data bus width. Voltage A (1.2V), B (1.1V), K (1.35V) Operating voltage requirements. Speed Grade -062E (DDR4-3200), -075 (DDR4-2666) Max frequency and timing (CL-tRCD-tRP). Die Revision :E , :B , :A The specific manufacturing "generation" or "die". 3.
