Samsung Electronics, the world's biggest maker of memory chips, said on Tuesday it remains cautious about the sector's outlook even as the industry emerges from its two-year slump.

Kwon Oh-hyun, head of the South Korean company's semiconductor business, also said through a translator he expects the current shortage of high-end DDR3 chips used in many PCs and other electronics devices to be resolved in the short term.

Kwon was speaking at the firm's annual mobile solutions forum in Taipei.

In July, Samsung Electronics, which also makes LCD screens and sells mobile phones and TVs carrying its own name, posted its best quarterly profit in 2-½ years.
