Description
The V58C2256(804/404/164)SA 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)SA 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 occurring on both edges of DQS.
Operating the four memory banks in an interleaved
fashion allows random access operation to occur at a
higher rate than is possible with standard DRAMs. A se-
quential and gapless data rate is possible depending on
burst length, CAS latency and speed grade of the device.
