Electic Tech schrijft dat Fujitsu vandaag een paar nieuwe FCRAM chips heeft geïntroduceerd. FCRAM onderscheid zich niet van normaal (DDR) SDRAM door een hogere bandbreedte, maar door significant lagere latencies wat natuurlijk minstens zo belangrijk is. Er komen twee smaken chips op de markt, de A en B serie. De chips uit de A serie lopen tussen de 133 en 154MHz en de chips uit de B serie lopen tussen de 167 en 200MHz. De eerste samples uit de A serie worden verwacht in het tweede kwartaal van dit jaar en zullen 100 dollar per stuk gaan kosten:
Fujitsu Microelectronics, Inc. (FMI) today introduced the latest members of its Fast Cycle RAM (FCRAM(TM)) series, a group of 256 Mbit, high-speed memories that incorporate the Double Data Rate (DDR) SDRAM interface.
The new FCRAMs, which were jointly developed with Toshiba, are designed for high-performance network systems that require very high capacities and speeds of 150MHz or more. The FCRAMs are ideal for applications that demand speeds higher than memory products currently provide, such as enterprise servers, look-up tables and high-speed buffers for network systems.
The new 2.5V FCRAMs are divided into the A Series (which feature 154MHz clock speeds) and the B Series (with 200MHz clock speeds). Both series use the SSTL-II I/O interface. Cycle times for different versions of the A series range from 30ns to 40ns; access times range from under 23ns to 30ns. For the B Series, cycle times range from 25ns to 40ns; access times are from 22ns to 30ns.
