GENERAL DESCRIPTION

The K4S641632C is 67,108,864 bits synchronous high data

rate Dynamic RAM organized as 4 x 1,048,576 words by 16

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, programma-

ble burst length and programmable latencies allow the same

device to be useful for a variety of high bandwidth, high perfor-

mance memory system applications.
