256M GDDR SDRAM
K4D553238F-JC
2M x 32Bit x 4 Banks Graphic Double Data Rate Synchronous DRAM
with Bi-directional Data Strobe and DLL
- 3 -
Rev 1.0 (Mar. 2004)
The K4D553238F is 268,435,456 bits of hyper synchronous data rate Dynamic RAM organized as 4 x 2,097,152 words by
32 bits, fabricated with SAMSUNG
s high performance CMOS technology. Synchronous features with Data Strobe allow
extremely high performance up to 2.8GB/s/chip. I/O transactions are possible on both edges of the clock cycle. 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.
2.5V + 5% power supply for device operation
2.5V + 5% power supply for I/O interface
SSTL_2 compatible inputs/outputs
4 banks operation
MRS cycle with address key programs
-. Read latency 3, 4 (clock)
-. Burst length (2, 4 and 8)
