Taiwan is ready for PC-100
David Manners This month Powerchip Semiconductor of Taiwan starts running wafers on its its 0.25?m process to make PC-100 64Mbit DRAMs. “In our case our 0.25?m 64Mbit DRAM will be 100 per cent PC-100 compatible,” said Dr Ben Tseng, vice-president for R&D at Powerchip. “Mitsubishi’s 0.25?m process [being run at Powerchip] has already been certified by Intel.” Powerchip will go down the double data rate (DDR) route for the microprocessor interface on its DRAMs, but does not see DDR as being usable for main memory – unless Intel decides to come out in support of it. Rambus is an alternative option for Powerchip but the cost of a licence ($5-$7m) is a lot for a start-up company. “A Rambus licence would be a lot of money for us,” said Tseng. Powerchip has the option of using Mitsubishi’s Rambus licence to make Rambus PC-100 DRAMs under sub-contract. The third option is SyncLink. “If, in the next two to three years, Rambus doesn’t assume a dominant position then I think SyncLink will have a damn good chance,” added Tseng.
