What is FCRAM (Fast Cycle RAM) Memory?

FCRAM (Fast Cycle RAM) was a technology developed by the Fujitsu Corporation in the early 2000s that approached the problem of DRAM/Processor speed in a different way. With the improvements in CPU speeds over the last few years, designers have looked for a solution that would get them over the ever present problem of relative slower memory.

Traditionally, various technologies such as EDO and SDRAM have attacked the problem with enhanced logic circuitry and peripherals that accessed the DRAM core. This resulted in the small advances that we have seen lately, but these advances were only targetting the interface to the DRAM, nothing else.

FCRAM, however, seeks to change the DRAM core itself. The process includes core segmentation and pipeline operation with the added benefit of power reduction. This new structure has introduced some significant advantages over traditional memory technology whose core has remained virtually unchanged in the last two decades. One such advantage will be the ability to send Row and Column information at the same time, as opposed to the standard sequential operation; in fact, a secondary command can be issued without needing to wait for the primary command to be completed. In combination with a DDR interface, this technology will speed performance significantly.

Joining the venture will be Toshiba Electronic Components. Both groups hope to make a definite change in the industry by providing an ample supply and keeping close customer relations to optimize their products. They plan on targetting these devices to high graphics-based systems and multimedia applications where a true difference in speed can be recognized.
