GENERAL DESCRIPTION
The K4S560432E / K4S560832E / K4S561632E is 268,435,456 bits synchronous high data rate Dynamic RAM organized as 4 x
16,785,216 / 4 x 8,392,608 / 4 x 4,196,304 words by 4bits, fabricated with SAMSUNG's high performance CMOS technology. Synchro-
nous design allows precise cycle control with the use of system clock I/O transactions are possible on every clock cycle. Range of oper-
ating 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.
