  • What is the difference between SDRAM and DDR?
SDRAM is actually SDR SDRAM, and DDR is actually DDR SDRAM, though the former does not usually have the SDR in front of it. The letters SDR and DDR stand for Single Data Rate and Double Data Rate, and the letters SDRAM stand for Synchronous Dynamic Random Access Memory. There are a lot of little differences, except the voltage they use are different,the main one that affects the user is speed:

DDR can transfer data at roughly twice the speed of SDR.
More speedy data rates = better performance.

  • What are the advantages of DDR3 memory modules?

DDR3 is the successor to DDR2 and DDR memory technology. DDR3 can break the GHz barrier with ease and is unmatched in bandwidth performances. DDR3 memory modules advantages are ultra fast speed, greater bandwidth, lower power consumption and better heat dissipation capabilities. The original design purpose for DDR3 memory modules were to work coincide with quad-core CPUs for maximum computing performance.

For actual applications, DDR3 is best suited to serve on high end PCs, workstations and servers where massive data processing is required. DDR3 memory module’s Column Write Delay (CWD) can also improve the bus command efficiencies used in servers. Additional bonuses of DDR3 technology is its low power consumption resulting in longer battery life for notebooks and its performance for HD content playback.

  • What are the advantages of FBGA style chips?

FBGA is a smaller package with requires less real estate on the memory module. In other words, more chips can fit onto a shorter module. The greatest benefit of FBGA is that it has less electricalnoise than TSOP chips, which results in improved signal integrity.

DDR3 technology is its low power consumption resulting in longer battery life for notebooks and its performance for HD content playback.
