GENERAL DESCRIPTION
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.
