The K4S280432F / K4S280832F / K4S281632F is 134,217,728 bits synchronous high data rate Dynamic RAM organized as 4 x
8,388,608 words by 4 bits / 4 x 4,194,304 words by 8 bits / 4 x 2,097,152 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.
