K4S643232H
CMOS SDRAM
3 -
SDRAM 64Mb H-die (x32)
The K4S643232H is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x 524,288 words by 32 bits, fabricated
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 length and programmable
latencies allow the same device to be useful for a variety of high bandwidth, high performance memory system applications.
