Keywords:DDR3? SDRAM? III IV Stratix?

DDR3 SDRAM is the latest generation of DDR SDRAM technology, with improvements that include lower power consumption, higher data bandwidth, enhanced signal quality with multiple on-die termination (ODT) selection and output driver impedance control.

DDR3 SDRAM brings higher memory performance to a broad range of applications, such as

PCs, embedded processor systems, image processing, storage, communications, and networking.

Although DDR2 SDRAM is currently the more popular SDRAM, to save system power and increase system performance you should consider using DDR3 SDRAM. DDR3 SDRAM offers lower power by using 1.5V for the supply and I/O voltage compared to the 1.8V supply and I/O voltage used by DDR2 SDRAM. DDR3 SDRAM also has better maximum throughput compared to DDR2 SDRAM by increasing the data rate per pin and the number of banks (8 banks are standard).
