NEW YORK, USA: Marvell Technology Group Ltd chief executive Sehat Sutardja said that he expects multimedia-enabled smartphones to account for at least 50 percent of all cellphones in the next three to four years, and grow even more popular in the following years.

"Smartphones today are only addressing the tip of the pyramid," Sutardja told the Reuters Global Technology Summit.

"I would say in the next three to four years, at least 50 percent of the market will move to smartphones," he said, adding that may grow to 90 percent in six to seven years.

Sutardja also said it was hard to tell if technology demand was recovering, noting it was hard to distinguish between temporary moves to replenish inventory and a real rebound in demand.
