SDram & Dram

What's the difference between SDram and Dram

[Bob The Great]

In short. SDram (Synchronous Dynamic Random Access Memory) is slower, and cheaper. DRam (Dynamic Random Access Memory) is faster, and more expensive. For a more indepth comparision do a search at http://www.google.com

Wait a minute... I believe you have that backward...

SDRAM is a huge improvement over other types of DRAM (Fast Page & EDO) because the memory operations are syncronized with the processor clock. SDRAM (7.5-10ns) is about 8 times faster than regular DRAM (50ns). Yes, SDRAM is dirt cheap compared to older FPM and EDO DRAM modules, which are very expensive.

DRAM is primarily found on 72-pin FPM and EDO SIMM modules. SDRAM is what is used on the common 168-pin DIMM modules (anything classified as PC66/100/133/150 is SDRAM)

The newest type memory is DDR, which is still SDRAM (synchronous dynamic random access memory), but can move data at Double the Data Rate of regular SDRAM, it also requires a mobo equiped with 184-pin DIMM slots.

The S-Files (http://www.crucial.com/library/sfiles1.asp) at Crucial.com is a good place to start learning about the evolution of DRAM and SDRAM.

Also an excellent source of info and quality ram can be found here at Corsair. http://www.corsairmicro.com/main/products.htm
