In the world of semiconductor engineering, a component’s part number is far more than a mere inventory label. It is a dense, cryptic shorthand that encodes the device’s entire technical identity—its density, architecture, speed, package, temperature range, and compliance status. For memory products from Micron Technology, one of the world’s largest manufacturers of DRAM and NAND flash, decoding this alphanumeric string is an essential skill for hardware designers, purchasing agents, and firmware engineers. The Micron memory part number decoder is not a physical tool but a systematic methodology—a logical key to unlocking the specifications hidden within a 15- to 25-character part number. Mastering this decoder allows one to determine compatibility, optimize system performance, and avoid costly design errors.
| 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 |
Micron’s part numbering system has evolved over decades, shaped by industry standards (such as JEDEC) and the need for global, unambiguous communication. Unlike some competitors that use separate numbering families, Micron maintains a relatively consistent logic across its major product lines: DDR SDRAM, LPDDR, GDDR, and NAND flash (including discrete NAND and eMMC). The decoder is essentially a parsing engine that divides the part number into fields—each field representing a specific attribute. While minor variations exist between product families and generations (e.g., DDR4 vs. DDR5), the core syntax follows a predictable pattern. micron memory part number decoder
