NEC Corp. on Monday introduced a next generation family of DDR-II SRAMs and Quad-Data-Rate (QDL-II) SRAMs for communications and networking applications.
Officials said the higher bandwidth SRAMs support the new higher speed OC-192 and OC-768 network standards. Single I/O DDR-II or two data ports QDR-II that support burst length of two or four are optimized for data-streaming network products.
The first configurations are 18-megabit at 33-MHz. A 36-Mbit version is planned for an unspecified debut in the future.
Samples of both type SRAMs are available at $80 each. Production quantities and pricing are scheduled for Q3 '02.
Separately, NEC said it was tripling its production to 20 million units this fiscal year (started April 1) of USB2.0 chips. NEC claimed it already held a 90% market share of USB2.0 chips. The new USB2.0 standard has data throughput of 480-megabits/second, 40 times faster than the first generation format.
