fast cycle RAM (FCRAM)

Fast Cycle RAM technology(FCRAM) is a RAM technology developed by Fujitsu with which DRAM cores are modified so that they have the properties of Static RAMs( SRAM).

These characteristics enable higher data transfer rates and better adaptation to processor speed than DRAMs. FCRAM technology seeks to modify the DRAM core itself. This process involves core segmentation and pipelining with the advantage of power reduction.

The core structure of FCRAMs has its own pipeline concept and a hidden pre-charge with which the random access cycle is reduced in time to less than half the access time of Synchronous Dynamic RAMs( SDRAM) or Rambus DRAMs. As a result, the FCRAM structure has significant advantages over traditional memory structures, one of which is the simultaneous transfer of column and row information with one command. A second command can already be issued without the first command being completed. Inconjunction with a DDR interface, this considerably increases the processing speed.
