What Is SODIMM?
Small outline dual in-line memory module (SODIMM or SO-DIMM) is a type of random access memory (RAM). It is a smaller version of a dual in-line memory module (DIMM). SODIMM is made of integrated circuits attached to both sides of a printed circuit board.

Function
-
Because SODIMM is approximately half the size of DIMM, it is useful in limited space devices. SODIMM is commonly found in mobile computing and other devices such as laptops, routers and networked printers. It is also often used in devices with low power consumption requirements.
Memory
-
SODIMMs come in three classes of memory: DDR SDRAM (double data rate synchronous dynamic random access memory), DDR2 SDRAM and DDR3 SDRAM. The different types of SODIMM memory are not compatible with each other and will only fit within a type-specified slot within a device. SODIMM memory capacity typically ranges from 4 MB to 32 GB.

DIMM Family
-
DIMM are dynamic random access memory (DRAM) integrated circuits attached to both sides of a printed circuit board. They are characterized by having separate contacts on each side of the board (in contrast to DIMM's predecessor, SIMM, or single in-line memory module, which duplicates the contacts on each side of the module).
Technical Information
-
SODIMMs are available in 72, 100,144, 200 and 204 pin count. The 72 and 100 pin count modules have a 32-bit data transfer rate. The 144, 200 and 204 pin count modules have a 64-bit transfer rate.
Size
-
The average size of a SODIMM is 2.6 inches by 1.25 inches.
