Silicon Motion Technology saw its revenues climb to a record high of US$289 million in 2014, thanks to strong growth in sales generated from its eMMC controller business, according to the flash storage controller company.

Silicon Motion disclosed that sales of its eMMC controllers account for about 40% of company revenues. Rising sales of Silicon Motion's eMMC products led to a revenue increase of 28.4% on year in 2014, the company noted.

In the fourth quarter of 2014, Silicon Motion generated revenues of US$80.5 million and a gross margin of 52.5%. Net profits for the quarter came to US$16.57 million, or US$0.48 per diluted ADS.

"Our fourth quarter revenue increased 53% as compared to the fourth quarter of 2013, led by a strong 70% on-year increase of our embedded storage sales, with strong growth by our eMMC and client SSD controllers," Silicon Motion president and CEO Wallace Kou indicated.

Kou added that sales of Silicon Motion's embedded storage products, which consist primarily of eMMC, client SSD and industrial SSD controllers, have grown to account for over half of the company's total sales.

In addition, Silicon Motion disclosed that the company has begun shipments of its SATA3 client SSD controllers to Micron Technology and another NAND flash OEM. The flash storage controller supplier also revealed that its storage OEM customer began shipping SSDs with its SATA3 client SSD controllers to three global tier-1 PC OEMs.

"We secured an SSD platform win at another NAND flash OEM, which brings the total number of NAND flash partners that will enter production in 2015 with our client SSD controllers to four," noted Kou.

Furthermore, Silicon Motion will begin shipments of its TLC SATA 3 client SSD controller to several module makers in the first quarter of 2015, the company said.

Silicon Motion expects revenues to stay flat or decrease up to 5% sequentially in the first quarter of 2015. For all of the year, the company forecast a 15-25% revenue increase.

"2014 was an outstanding year for Silicon Motion. We believe our strong 2014 sets the stage for continuing growth in 2015. We are confident that our SK Hynix eMMC business will continue to grow and our client SSD controller sales will scale as our OEM projects enter production," Kou said.
