Samsung predicts very strong demand for computer memory chips in the first quarter of next year, mainly because of the release of Windows Vista in January.
Chu said demand and prices for DRAM chips, used mostly in personal computers, were strong in the fourth quarter and saw the market for NAND memory chips, popular in digital cameras, stabilising as well.
Chip and PC makers have been eagerly awaiting the release of Microsoft's Vista operating system as consumers have been delaying the purchase of new PCs for the same reason.
Microsoft said last week Vista would be available to retail customers on January 30. The announcement dispelled worries the software giant would delay it again.
