  • UMC Prepares for System-on-a-Chip Trend
  • August 21, 1998 (TAIPEI) -- United Microelectronics Corp. (UMC) began R&D; of higher-level dynamic random access memory (DRAM) products to prepare for the future trend of system-on-a-chip.
    System-on-a-chip technology is the most advanced in Europe.

    The United States has been slower in this field, and application in Japan is mostly seen in consumer electronics.

    It is expected that in the future, embedded flash memory and embedded memory can be integrated into one simple system-on-a-chip.

    UMC has adopted 0.3-micron manufacturing technology in its 64Mb DRAM production.

    The company is scheduled to start mass production of 64Mb DRAMs using 0.25-micron technology around the end of 1998.

    UMC also is researching 0.21-micron technology.

    As for embedded products, the company is integrating DRAMs with logic products so that the two can be made compatible.

    UMC has begun mass production of 0.35-micron embedded DRAMs.

    Currently, UMC is devoted to the R&D; of 0.25-micron embedded DRAMs.

    Because production costs for embedded DRAMs are higher than those of traditional DRAMs and logic products, embedded DRAMs must be applied to products with high added-value. Its functions and performance must be special enough for such high production costs.

    Embedded memory is a link to the system-on-a-chip. Embedded static random access memory (SRAM) manufacturing has been standardized, but it is more difficult to produce embedded DRAMs.
