K4S64323LF-S(D)N/U/P
Rev. 1.5 Dec 2002
CMOS SDRAM
The K4S64323LF is 67,108,864 bits synchronous high data rate
Dynamic RAM organized as 4 x 524,288 words by 32 bits, fabri-
cated with SAMSUNG
s high performance 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 lengths and
programmable latencies allow the same device to be useful for a
variety of high bandwidth and high performance memory system
applications.
