Hitachi spin-off, Elpida, eyes SDRAMs
Sep. 29, 2000 (Electronic Engineering Times - CMP via COMTEX) -- TOKYO - Nearly a year after shaking hands on the deal, Hitachi Ltd. and NEC Corp. last week announced the name and product strategy of their jointly owned DRAM company. The 50-50 owned spin-off, Elpida Memory Inc., will open its doors for business at the start of next year, and has high hopes of capturing a 20 percent market share in the next few years. Yet executives left unanswered a number of questions about product and capacity plans.
At a press conference, Elpida president Kenji Tokuyama and executive vice president Tokumasa Yasui, who hail from NEC and Hitachi, respectively, emphasized Elpida's intention to quickly move to 0.13-micron line widths. That process technology will provide the underpinning for jointly developed 256-Mbit DRAMs that will be introduced by the second quarter of next year.
SDRAM vs. Rambus
In his presentation, Yasui highlighted Elpida's planned move to 256 Mbits in the first half of 2001, starting with 133- and 166-MHz synchronous DRAMs and double-data-rate (DDR) SDRAMs. A NEC-developed technology, 256-Mbit virtual-channel DRAM, is also scheduled to be introduced in the second quarter. And by around mid-2002, Elpida expects to introduce a faster version of DDR known as DDR-2.
Less clear is Elpida's Rambus plans. The company's 256-Mbit Rambus DRAM, based on 0.13-micron design rules, is slated to come out in the fourth quarter of 2001, according to the road map Yasui presented. However, this differed from a road map later provided to the press, which showed the 0.13-micron 256-Mbit RDRAM being introduced at the same time as the DDR and SDRAM products.
The discrepancy stems from unresolved licensing and royalty issues between Rambus and the new company, an Elpida spokesman said. Both Hitachi and NEC have signed royalty payment agreements with Rambus Inc. covering RDRAM, SDRAM and DDR technologies, but those are due to expire by year's end when Elpida takes over the product line. "We don't have a strict schedule for Rambus [DRAM] because we need to get an agreement with Rambus," an Elpida spokesman said. "We are trying to start negotiations that will influence the start of the development."
Yasui said he'd like to come to terms with Rambus before the end of the year, a schedule that would avoid the legal battle that has erupted between Rambus and memory makers Micron, Infineon and Hyundai.
Hitachi, which ended a bitter legal dispute with Rambus earlier this year by agreeing to pay the SDRAM and DDR royalties, is not producing RDRAM. NEC, however, this year became one of the first to introduce an 0.18-micron 288-Mbit RDRAM, and has championed the part for high-end workstations.
Elpida's emphasis on a faster SDRAM and on DDR may complicate negotiations with Rambus. As a way to encourage greater RDRAM production, Rambus' strategy is to charge the highest royalties for DDR, less for RDRAM and still less for SDRAM.
Rambus considers standard SDRAM a moribund technology and no threat to RDRAM. Not so with DDR, however. "The reason we're asking for higher royalty on DDR is because we feel it was introduced to compete with RDRAM using innovations created for RDRAM," said Avo Kanadjian, vice president of marketing for Rambus, in a recent interview.
As Elpida works to resolve its Rambus question, it is considering ways to build up enough manufacturing muscle to compete against bigger rivals Samsung, Hyundai and Micron. Last year, NEC and Hitachi together accounted for 13.6 percent of the DRAM market, and Elpida's goal is to reach 20 percent by 2003. Yet even with the upswing in DRAM prices this year, Elpida's sales forecast of $3.25 billion-made last November for fiscal 2001-has not changed.
Elpida officials acknowledge they are behind the big-three DRAM makers in terms of capacity, and are urging their parent companies to increase volume. One way is to use 300-mm wafers, a move now being planned for at NEC's high-volume DRAM plant in Hiroshima starting in the second half of 2002. Another way is by being early to make process technology shrinks. Indeed, Elpida claims it will be the first to market 0.13-micron-based 256-Mbit DRAMs, which should have half the die size of today's leading-edge 0.18-micron devices. The shift to 0.11 micron at NEC's Hiroshima plant is scheduled to begin by the second half of 2001.
Right now, the two main DRAM plants owned by Hitachi and NEC together are producing 50,000 wafers per month. NEC's Hiroshima plant is expected to reach 60,000 wafers a month by the end of this year, and will more or less stay at that level for two years, until the 300-mm wafer line is introduced in the second half of 2002. No data was provided for Hitachi's main DRAM fab in Singapore.
While sales, product development and R&D have shifted to Elpida, the fabs remain under control of the parent companies. And even though NEC and Hitachi have pumped up their semiconductor capital spending this year, Japan's chip companies tend to spend more on logic and system-on-chip technologies than on DRAM.
Accordingly, Elpida executives are talking more about turning a profit than turning up production volumes. Yasui said the question is "how to get a good profit with certain capacity. Basically we need to concentrate on the server market."
One way to crank up capacity would be for Elpida to build its own fab, an option that is being considered. "In the future, in order for us to be good in the DRAM business we need to think about having our own capacity," Yasui said. Given that new fabs cost well over $1 billion, such a move would require a huge capital investment and, possibly, an initial public offering. "In order to get the money to invest and to encourage people we need to think about an IPO," Yasui said.
Another option would be for Elpida to buy the DRAM fabs from NEC and Hitachi outright, but the Japanese tax code discourages the transfer of large assets to other companies, said Masahiko Ogirima, senior vice president of Hitachi.
Meanwhile, Elpida is moving forward with plans to consolidate its sales and administration operations. Taking into account both parents' worldwide sales divisions, the new company will reduce its sales force head count by 30 percent globally. A Hitachi spokesman was unsure how many employees affected by the cut would be transferred to other positions or laid off.
Elpida plans to employ a total of 750 people, 500 of them in product design and development, and based in Japan.
