Represents the maximum transfer speed in megatransfers per second (MT/s) or nanoseconds.
Understanding how to read this code is essential for engineers, procurement specialists, and tech enthusiasts. This guide will break down the Micron memory part number decoder system so you can identify any Micron chip instantly. Why Decoding Micron Part Numbers Matters
The next letters tell you the generation of the memory and how much power it needs. : This can mean standard DDR4 memory. B : This can mean DDR5 memory. L : This letter means "Low Voltage" to save power. 3. Capacity and Configuration
| Field | Code | Meaning | |-------|------|---------| | Base | MT40A | DDR4 SDRAM (40A = DDR4, 40B = DDR4 with different features) | | Density | 512M | 512 Megabits (total per chip). Multiply by organization to get device density. | | Organization | 16 | x16 (data width in bits) | | Package | JY | J = 78-ball BGA, Y = Pb-free, Halogen-free | | Speed Grade | -083E | 083 = 8-8-8 (DDR4-2400), E = DRAM revision | | Revision | :B | B-die revision | micron memory part number decoder
Identify family → find density/organization → map speed/voltage code → read package/temp → confirm revision/assembly.
If you need help identifying a specific component, please share the or the 5-digit FBGA code printed on your chip. I can also break down the precise pin layout or timing latencies for a particular memory generation if needed. Share public link
: Commonly found on the bottom line of text on a chip, these 5-character codes (e.g., D9WFL) are essential for finding the actual part number. Represents the maximum transfer speed in megatransfers per

Understanding the part number ensures you select the correct component for your application, preventing costly design errors.
Micron uses a highly structured part numbering system to identify memory components and modules. Because physical chips are often too small for full part numbers, Micron also utilizes a five-digit (also known as a D9 code) as an abbreviated identifier.

| 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 Technology is a global leader in semiconductor systems, producing vast quantities of DRAM, NAND flash, and solid-state storage. If you have ever looked at a Micron memory module or chip, you have likely seen a complex string of alphanumeric characters printed on the surface.
