K4H560438D
16M x 4Bit x 4 Banks Double Data Rate SDRAM
GENERAL DESCRIPTION
DDR SDRAM
The K4H560438D is 268,435,456 bits of double data rate synchronous DRAM organized as 4 x 16,777,216 words by 4 bits, fabricated
with SAMSUNG鈥瞫 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.
