GENERAL DESCRIPTION
rate Dynamic RAM organized as 2 x 524,288 words by 16 bits,
fabricated with SAMSUNG′s high performance CMOS technol-
ogy. 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 mem-
ory system applications.
