SODIMM types refer to the various form factors and specifications of Small Outline Dual In-line Memory Modules, commonly used in laptops and other compact devices. These modules are smaller than their DIMM counterparts found in desktop computers. The primary distinctions between SODIMM types lie in their physical dimensions, pin counts, and electrical signaling.

Early SODIMMs utilized DDR, DDR2, and DDR3 technologies. DDR SODIMMs have 144 pins and a distinct notch placement to prevent incorrect installation. DDR2 SODIMMs feature 200 pins, also with a specific notch position. DDR3 SODIMMs increase the pin count to 204, again with a unique notch.

The most current standard is DDR4 SODIMM, which has 260 pins. DDR5 SODIMMs are also emerging, offering even higher performance and efficiency with 262 pins. Each generation offers increased data transfer rates and often lower power consumption.

Compatibility is crucial when selecting SODIMMs. A motherboard or laptop is designed to accept a specific type of SODIMM; mixing types will result in the module not fitting or not functioning. It is essential to consult the device's specifications or the motherboard manual to determine the correct SODIMM type required.
