NEC Electronics Ships QDRII/DDRII Family of High-Speed SRAM
Products
TOKYO and SANTA CLARA, Calif., April 15, 2002 - NEC
Corp. (NASDAQ: NIPNY) and its wholly owned subsidiary in the
United States, NEC Electronics Inc., today announced the availability
of their Quad Data Rate (QDRT) II and Double Data Rate (DDR)
II family of static random access memory (SRAM) products.
These products are fully compliant with the second-generation
of high-performance QDR and DDR communication memory standards
for network switches, routers and other communications applications.
"Emerging network standards like OC-192 and OC-768 are becoming
increasingly popular in the network switch and router markets,
and the data rates required to support these standards are
beyond the limits of conventional SRAM technologies, " said
SJ Han, senior manager for memory engineering and marketing,
NEC Electronics Inc. "NEC is proud to be one of a handful
of vendors currently shipping this leading-edge memory technology."
The first of NEC's QDR II / DDR II products is available
in an 18-megabit (Mb) configuration, with a 36 Mb version
scheduled for future availability. Additionally, NEC's QDR
II/DDR II family of SRAM products is available with input/output
(I/O) configurations that support either a burst length of
two or a burst length of four.
NEC's 18 Mb QDR II SRAM devices use the QDR II-standard 165-pin,
13 millimeter (mm) x 15mm fine-pitch, ball-grid array (FBGA)
packaging, providing significant space savings and shorter
bus lengths for minimized delays, skews and electromagnetic
interference (EMI). The products also feature a low 1.8-volt
power source to accommodate the stringent power specifications
characteristic of high-end routers and switches. The devices
also provide an unprecedented data valid window of 65 percent
of the clock cycle or a 1.3-nanosecond data valid window at
250 megahertz (MHz).
About QDR II / DDR II SRAMs
QDR II and DDR II SRAMs enable system designers to maximize
bandwidth in data-intensive communication applications by
allowing operation speeds of up to 333 MHz. The QDR II architecture
features two data ports (input and output) operating twice
per clock cycle to deliver a total of four data instructions
per cycle. The resulting performance increase is particularly
valuable for high-end communications applications, where the
fast movement of large amounts of data is essential. Single
I/O DDR II devices allow double data rate transfers over the
I/O data bus and are optimized for data-streaming operations.
The QDR II / DDR II SRAM specification is popular with many
network processor vendors, and several network processors
are now available with QDR II interfaces. The QDR II and DDR
II specification was mutually defined, developed and delivered
by the QDR Co-Development Team for the high-speed networking
market.
Pricing and Availability
Engineering samples of NEC's first QDR II / DDR II SRAM products
are available now with a sample price of $80, and production-level
availability scheduled for third quarter 2002. The chart below
illustrates NEC's QDR II and DDR II offerings, including burst
length, memory configuration and part numbers.

About the QDR Co-Development Team
In 1999, the QDR Co-Development Team was created to define
a new family of SRAM architectures for high-performance communications
applications. The QDR Co-Development Team currently consists
of Cypress, IDT, Micron, NEC, Samsung and Hitachi. These companies
cooperate in the development of the QDR family of networking
SRAMs. They design and manufacture this family of products
in their own fabrication facilities and develop products according
to their own schedules, competing in the marketplace. Additional
information on the QDR SRAM technologies, including roadmaps,
is available at http://www.qdrsram.com/.
