Product Summary

The K4H561638J-LCB3 is a double data rate synchronous DRAM organized as 4x 8,388,608 words by 8bits. It is fabricated with SAMSUNG’s high performance CMOS technology. Synchronous features with Data Strobe allow extremely high performance up to 400Mb/s per pin. I/O transactions are possible on both edges of DQS. Range of operating frequencies, programmable burst length and programmable latencies allow the K4H561638J-LCB3 to be useful for a variety of high performance memory system applications.
