2-3. 256Mbit SDRAM (K4S561633C-RL75)
(1) DESCRIPTION
The K4S561633C is 268, 435, 456 bits synchronous high data rate
Dynamic RAM organized as 4 x 4, 196, 304 words by 16 bits, fabricated
with SAMSUNG's high performance CMOS technology. Synchronous
design allows precise cycle control with the use of system clock and I/O
transactions are possible on every clock cycle. Range of operating fre-
quencies, programmable burst length and programmable latencies
allow the same device to be useful for a variety of high bandwidth, high
performance memory system applications.
