Fujitsu has developed a new type of computer memory called the Fast Cycle Random Access Memory (FCRAM). The company plans to put the chip, said to be based on a newly designed core, into machines in 2000.
With a 20 nanosecond0 cycle time four times faster than current processors the FCRAM will be aimed at multimedia processing of 3D images. It has a 64Mb capacity, but Fujitsu will develop higher density versions.
Features that make the chip faster than existing DRAM or SSRAM are:
the processor addresses the rows and columns of the memory matrix simultaneously to achieve the 20ns cycle time;
an automatic reset circuit, which allows continuous data processing. An address command for a successive cycle is initiated in the preceding cycle while the current command is being processed.
Power consumption is said to be relatively low, making the FCRAM suitable for battery operation.
