Micron Memory Part Number Decoder (Full HD)

This paper outlines the technical framework and methodology for decoding Micron Technology's memory part numbering systems. Technical Analysis: Micron Memory Part Number Decoding 1. Introduction to Micron Part Numbering

Micron divides its part numbers into distinct fields. While the exact breakdown varies slightly between volatile memory (DRAM) and non-volatile memory (NAND Flash), the standard framework generally spans 12 to 19 characters. The typical sequence follows this logic:

The complete technical string (e.g., MT40A512M16LY-062E:E ) used for ordering and locating datasheets. 2. How to Read Micron Part Numbers

| Segment (within MT48LC16M8A2TG-75 ) | Field Description | | :--- | :--- | | | Manufacturer: This prefix is common to almost all Micron memory products and simply stands for "Micron Technology". | | 48 | Product Family: This two-digit number indicates the type of memory. For example, 48 stands for SDRAM, 46 for DDR SDRAM, and 6 for RDRAM (Rambus DRAM). | | LC | Process Technology: These letters often indicate the operating voltage of the chip's core. For example, C represents a 5V CMOS process, while LC represents a 3.3V CMOS process. | | 16M | Depth: The capacity of the device is calculated by a formula: Depth x Width . In this example, 16M means the memory array is 16 Meg deep. | | 8 | Width: This number specifies the device's data width in bits. An 8 means the chip is organized as an 8-bit wide device. The full capacity is, therefore, 16M x 8 = 128 Megabits (Mb). | | A2 | Die Revision & Options: The A here typically indicates the die revision, and the following number ( 2 ) may indicate options like power-saving features. | | TG | Package Type: These two letters identify the physical package. TG stands for TSOPII (Thin Small Outline Package), but many other codes exist for BGA and other package types. | | -75 | Speed Grade: This number is the device's rated speed, often in nanoseconds (ns). -75 indicates an access time of 7.5ns (133 MHz operation). |

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. micron memory part number decoder

A single letter indicates the power requirements of the silicon: Standard Voltage (e.g., 1.2V for DDR4) K: Ultra-low voltage variants

: The full tracking string used for ordering and datasheets (e.g., MT40A2G8AG-062E:B ).

: The decoder is specifically for FBGA-packaged components. Standard modules (like DIMMs) typically use a Serial Presence-Detect (SPD) Lookup Mobile Experience

A standard Micron DRAM part number typically consists of 12 to 18 characters broken down into distinct fields: Description Example Component Identifies the product as Micron memory. MT 2. Tech Type Specifies the memory technology generation. 40A (DDR4) / 60B (DDR5) 3. Configuration Shows the density and bit organization. 4G4 (4 Gb x4) / 2G8 (2 Gb x8) 4. Attributes Details die revisions, voltages, and variants. N / M 5. Package Identifies the physical casing and pin layout. RH / HC 6. Speed Grade Dictates the clock cycle time and data transfer rate. -062E / -48BA 7. Special Markings Denotes processing, validation, or temperature ranges. :B / IT Step-by-Step Breakdown of Micron DRAM Part Numbers This paper outlines the technical framework and methodology

Micron often prints a short, five-character alphanumeric code (known as an FBGA code) directly onto smaller chips instead of the full part number.

Subsequent optimization shrinks (e.g., E-die or B-die), which often feature different overclocking ceilings and thermal profiles. Decoding Micron Flash and SSD Part Numbers

The first two letters indicate the manufacturer and product line.

Different variations of chip-scale packaging optimized for thermal efficiency. 6. Speed Grade / Clock Cycle Time While the exact breakdown varies slightly between volatile

Manually translating Micron part numbers protects your infrastructure from unexpected downtime. By understanding how to isolate the product family, density configuration, speed grade, and die revision, you can make informed decisions during hardware procurement, testing, and troubleshooting.
