'''Fast Cycle DRAM''' ('''FCRAM''') <!--The initialism is really "FCRAM"!--> is a type of [synchronous dynamic random-access memory](/source/synchronous_dynamic_random-access_memory) developed by [Fujitsu](/source/Fujitsu) and [Toshiba](/source/Toshiba). FCRAM has a shorter data access latency compared to contemporary commodity SDRAMs; and is used in where the lower data access latency is more desirable than low cost and high capacity (FCRAM is a moderate cost and capacity speciality DRAM). FCRAM achieves its low latency by dividing each row into multiple sub-rows, of which only one is activated during a row-activation operation. This reduced the effective array size, improving the access time. FCRAM has a [DDR SDRAM](/source/DDR_SDRAM)-like command set to enable memory controllers that support both DDR SDRAM and FCRAM. It also has a standard [dual in-line memory module](/source/dual_in-line_memory_module) (DIMM).
