FEATURES

GENERAL DESCRIPTION

4M x 16Bit x 4 Banks Synchronous DRAM in 54CSP

FUNCTIONAL BLOCK DIAGRAM

The K4S561633C is 268,435,456 bits synchronous high data rate

Dynamic RAM organized as 4 x 4,196,304 words by 16 bits, fabri-

cated with SAMSUNG's high performance CMOS technology. Syn-

chronous design allows precise cycle control with the use of

system clock and 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.
