GENERAL DESCRIPTION

The K4S64323LH is 67,108,864 bits synchronous high data rate Dynamic RAM organized as 4 x 524,288 words by 32 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 frequencies, programmable burst lengths and programmable latencies allow the same device to be useful for a variety of high bandwidth and high performance memory system applications.
