Revenue for the fourth quarter of 2016 was $97.6 million, up 9% on a sequential basis from the third quarter of 2016 primarily due to higher product revenue from the memory and interfaces business and higher royalty revenue.

Revenue for the year ended December 31, 2016 was $336.6 million, up 14% from the year ended December 31, 2015, which is primarily due to higher revenue from the security technology business and higher product revenue primarily from the memory and interfaces business.
