The K4H560838D is 268,435,456 bits of double data rate synchronous DRAM organized as 4 x 8,388,608 words by 8 bits, fabricated
with SAMSUNG
′
s high performance CMOS technology. Synchronous features with Data Strobe allow extremely high performance up
to 333Mb/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 device to be useful for a variety of high performance memory system applications.
