Description
The V58C365164S is a four bank DDR DRAM organized as 4 banks x 1Mbit x 16. The V58C365164S 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, address, circuits are synchronized with the positive edge of an externally supplied clock. I/O transactions are possible on both edges of DQS.
