K4S640832D
CMOS SDRAM
Rev. 0.0 May 1999
The K4S640832D is 67,108,864 bits synchronous high data
rate Dynamic RAM organized as 4 x 2,097,152 words by 8 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.
