FUNCTIONAL BLOCK DIAGRAM
GENERAL DESCRIPTION
The K4S561633C is 268,435,456 bits synchronous high data rate
Dynamic RAM organized as 4 x 4,196,304 words by 16 bits, fabri-
cated with SAMSUNG's high performance CMOS technology. Syn-
chronous design allows precise cycle control with the use of
system clock and 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.
