Rev. 2.2 Mar. ’03
K4H561638D
4M x 16Bit x 4 Banks Double Data Rate SDRAM
The K4H561638D is 268,435,456 bits of double data rate synchronous DRAM organized as 4 x 4,194,304 words by 16 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.
