GENERAL DESCRIPTION

The K4S160822D is 16,777,216 bits synchronous high data rate Dynamic RAM organized as 2 x 1,048,576 words by 8 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.
