    (1) Computer consists of ICs such as HDD controllers, DVD-ROM/CD-ROM
    drives ICs, LCD drivers, graphic processors, and PDAs. Communication
    consists of xDSL, DSP, WLAN, LAN controllers, handset components, caller
    ID devices, etc. Consumer consists of ICs used for DVD players, game
    consoles, digital cameras, smart cards, toys, etc. Memory consists of DRAM,
    SRAM, Flash, EPROM, ROM, and EEPROM.

All three major applications continued to grow in 3Q09. The computer and consumer segments outpaced communication segment growth since the latter had already experienced an earlier rebound in growth in 2Q09.
