"Micron has been highly engaged in M&A activities and strategic alliances over the past years. Those two approaches, though not new, have been able to help Micron obtain the most outcomes such as increased sales and profitability," says Hui-Chung Tu, industry analyst with MIC.

Micron's ability to spot good investment timing is another factor determining its success. Among all, perhaps the most noteworthy deployment of Micron is its deployment in DRAM. Micron has witnessed a strong uptake in DRAM and NAND flash businesses with its annual revenue breaking US$14 billion.

This has helped Micron land in top-five semiconductor vendors, next to Intel, Samsung, TSMC and Qualcomm. While the growth momentum continued well into 2014, Micron is expected to continue to cling to the fifth spot in 2015, as the global economy is showing promising signs.
