GENERAL DESCRIPTION
The K4S640432H / K4S640832H / K4S641632H is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x
4,194,304 words by 4 bits, / 4 x 2,097,152 words by 8 bits, / 4 x 1,048,576 words by 16 bits, fabricated with SAMSUNG′s high perfor-
mance 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.
