Three major DRAM makers -- Elpida Memory, Hynix Semiconductor and Infineon Technologies -- told the Jedex conference here Monday that they didn't plan to make 400-MHz speed memory in the DDR-I standard.
Samsung Electronics and Micron Technology within the last two weeks introduced DDR400 chips in the present DDR-I architecture. However, the remaining Big Five DRAM firms said they would wait for the next generation DDR-II standard to start sampling next year with 400MHz speed.
Joo Sun Choi, director of application marketing for Hynix Semiconductor America, San Jose, Calif., said trying to achieve 400-MHz with all its high speed challenges in the existing DDR-I standard "doesn't make sense."
Katsuyuki Sato, deputy general manager of technical marketing division for Elpida, said even if chip firms can make 400MHz DDR-I devices, it isn't clear that module vendors or motherboard suppliers would support such a memory.
