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 synchro-
nized with the positive edge of an externally sup-
plied clock. I/O transactions are possible on both
edges of DQS.
Operating the four memory banks in an inter-
leaved fashion allows random access operation to
occur at a higher rate than is possible with standard
DRAMs. A sequential and gapless data rate is pos-
sible depending on burst length, CAS latency and
speed grade of the device.
