In terms of Logic Products, the demands of the Motherboard Related I/O ICs and Embedded Controller continued to be strong due to hot season effects and the shipment of TFT-LCD also has shown good performance. However, the revenue of Speech ICs was down due to the traditional low season in October which caused a decrease on the overall revenue of Logic Products. In terms of Memory Products, the market demands of Pseudo SRAM and Specialty DRAM rose, and the supply was also stable.

As a whole, even though the fourth quarter is the traditional slow season for the consumer products, the demands of Notebook expect to still be strong. Therefore, the operational performance in the fourth quarter is anticipated to be stable.
