What is the difference between SDRAM & SODIMM MEMORY ?

Both are DIMM.

Wikipedia sums it up nicely:

"The main difference between SIMMs and DIMMs is that DIMMs have separate electrical contacts on each side of the module, while the contacts on SIMMs on both sides are redundant. Another difference is that standard SIMMs have a 32-bit data path, while standard DIMMs have a 64-bit data path. Since Intel's Pentium has (as do several other processors) a 64-bit bus width, it requires SIMMs installed in matched pairs in order to complete the data bus. The processor would then access the two SIMMs simultaneously. DIMMs were introduced to eliminate this practice."

I don't mean to rain on your answer but I think there is some confusion here.

SDRAM- Synchronous Dynamic Random Access Memory
SODIMM- Small Outline Dual In-line Memory Module

SDRAM & DIMMS are not "compariable" as their relationship is not competitive. Ie: Its like saying "What is the difference between a Ford and a car".

DIMM is the layout of the module. (dual in-line) SDRAM is the type of memory... SODIMM's are just smaller DIMMS (mostly used for laptops hence the smallness) but can still be SDRAM SODIMM...

"The latest 204-pin SO-DIMMs can contain DDR3 SDRAM, with specifications such as PC3-6400, PC3-8500, PC3-10600, and PC3-12800" -Wiki


Think of it this way. SDRAM can be mounted on a DIMM module. Or think of it this way, DIMM is the chasis of the car and SDRAM is the engine. :)

Do you understand?
