Micron Memory Part Number Decoder Today

If you see -40 anywhere in the suffix, that usually indicates -40°C operating range. Standard parts will not have that. For embedded systems, never substitute a commercial part for an industrial one.

If you work in IT procurement, system building, or hardware repair, you have likely stared at a string of alphanumeric characters on a RAM stick and wondered what it all means. Micron Technology—parent company of the consumer-facing brand Crucial—is one of the world’s largest manufacturers of DRAM, NAND, and SSD storage. Their part numbering system is complex but incredibly logical. micron memory part number decoder

Decoding a Micron memory part number is not just an academic exercise. It tells you the density, speed, voltage, package type, temperature rating, and environmental compliance of a component. Misreading it could result in buying an incompatible SODIMM for a laptop or using an industrial-grade chip in a consumer device (or vice versa). If you see -40 anywhere in the suffix,

This article serves as a complete Micron memory part number decoder—breaking down every segment of the code for DRAM modules, discrete DRAM components, and solid-state drives. Before we decode, a critical warning: Micron has

Before we decode, a critical warning: Micron has changed its numbering scheme over time. Legacy parts (DDR2/DDR3) use a slightly different syntax than modern DDR4/DDR5 or LPDRAM.

Always cross-reference your decoded guess with the official Micron datasheet. That said, the standard configuration follows a reliable pattern.

| Code | DDR Generation | Speed (MT/s) | CAS Latency | |------|----------------|--------------|---------------| | -062E | DDR4 | 3200 | CL22 | | -075E | DDR4 | 2666 | CL19 | | -083E | DDR4 | 2400 | CL17 | | -093E | DDR4 | 2133 | CL15 | | -062F | DDR5 | 4800 | CL40 | | -046F | DDR5 | 5600 | CL46 |
