GENERAL DESCRIPTION
5
data rate Dynamic RAM organized as 2 x 524,288 words by
32 bits, fabricated with high performance CMOS technology.
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.
