rate Dynamic RAM organized as 2 x 524,288 words by 32 bits,
fabricated
Synchronous design allows precise cycle control with the use of
system clock I/O transactions are possible on every clock cycle.
Range of operating frequencies, programmable burst length and
programmable latencies allow the same device to be useful for
a variety of high bandwidth, high performance memory system
applications.
