High-Speed FCRAM Incorporates DDR Interface

The newest members of the Fast Cycle RAM (FCRAM) series are 256 Mbit, high-speed memories that incorporate the double data rate (DDR) SDRAM interface. They are designed for high-performance network systems that require very high capacities and speeds of 150 MHz or more. The new 2.5V FCRAMs are divided into the A Series (MB81N261647A), which feature up to 154 MHz clock speeds, and the B Series (MB81N261647B), which feature up to 200 MHz clock speeds. Both series use the SSTL-II I/O interface. Cycle times for different versions of the A series range from 30 ns to 40 ns, while access times range from under 23 ns to 30 ns. For the B Series, cycle times range from 25 ns to 40 ns, while access times are from 22 ns to 30 ns. Pricing for the A Series begins at $100 each. FUJITSU MICROELECTRONICS INC. (800) 866-8608.
