  • [Electronics Show '98] Toshiba, Rohm Exhibit Logic ICs with Embedded DRAMs
  • October 12, 1998 (TOKYO) -- Toshiba Corp. introduced its roadmap for logic IC chips with embedded DRAMs at the Electronics Show '98 in Osaka.
    Development activities for embedded DRAM technology to install DRAMs on logic IC chips are becoming brisk among Japan's semiconductor makers,

    As for logic IC chips with embedded DRAMs, Toshiba will develop in 1999 an system IC, or system-on-a-chip, that includes its TX79 reduced-instruction set computer (RISC) microprocessor based on the MIPS architecture. The performance of the microprocessor is 400 million instructions per second (MIPS).

    For embedded flash memory, the company will develop a system chip that combines its MIPS architecture RISC microprocessor TX19 with memory in the first quarter of 1999. It will use a 0.4-micron process technology, 4Mb flash memory cores with a single power supply of 3.3V. The performance of the microprocessor is 20MIPS.

    Rohm Co. Ltd. showcased system chips that combined a ferroelectric memory and a DRAM or a flash memory with logic ICs. As in the past, company officials declined to provide details about ferroelectric memory products such as the date to start selling them. The company is introducing Mitsubishi Electric Corp.'s eRAM technology into its DRAMs.
