Fujitsu has announced the development of a form of SDRAM that can transfer data twice as fast as standard SDRAM. Double Data Rate SDRAM uses a new circuit architecture, and samples will begin shipping in November. According to Fujitsu, DDR (Deutsche Demokratik Republik? Surely not - ed.) SDRAM has a peak data transfer rate of 200 megabits per second for the device (x 8 I/O configuration) and 1.6 gigabits per second for the modules. The products incorporate an on-chip DLL circuit which allows the data output signal to be fully synchronised with the clock, and therefore improves clock access time. The company is aiming the new 64 megabit modules at high-speed system designs. they come in four variations, supporting non-ECC and ECC, and in 64-bit and 72-bit I/O formats. ® Click for more stories
