Fujitsu Ltd. On Wednesday said it has developed what it claims is the electronics industry's first single-chip 12-port 10Gbits/s Ethernet switch.
The Japanese chipmaker said the chip can replace current large 10Gbits/s Ethernet switches that are too bulky and expensive for cluster blade servers, or servers and storage units. The new chip is expected to enter production sometime this year.
Details of the 10Gbits/s Ethernet switch will be presented at the Hot Chips Symposium in Palo Alto, Calif., in August.
The chip size is 256mm sq., and integrates 12 Ethernet ports, high-speed buffer memory and a crossbar. The shared memory can handle read and write operations simultaneously for all 10Gbits/s ports.
The memory controller on the chip reduces latency to 450ns, or less than one-quarter the latency of existing switches, according to Fujitsu.
The chip was developed by Fujitsu Laboratories of America, Sunnyvale, Calif., in conjunction with Fujitsu Laboratories Ltd. of Japan.
Separately, Fujitsu on Wednesday also announced two new mobile Fast Cycle RAM chips with burst mode read/write operations.
The firm said the new 66 MHz burst mode will have 12ns clock access time in the read mode, offering higher data rates for new generation mobile phones with video data streaming and multimedia applications.
The burst mode FCRAM chips are available in 32 Mbit and 64 Mbit densities and samples are shipping now.
The new FCRAMs come as either stand-alone chips or mounted in a stacked multichip package with flash memory.
