The V58C2256(804/404/164)S is a four bank DDR DRAM organized as 4 banks x 8Mbit x 8 (804), 4 banks x 4Mbit x 16 (164), or 4 banks x 16Mbit x 4 (404). The V58C2256(804/404/164)S achieves high speed data transfer rates by employing a chip architecture that prefetches multiple bits and then synchronizes the output data to a system clock. All of the control, add.
