SODIMM stands for “Small Outline Dual In-Line Memory Module.” It is a type of computer memory module that is most commonly used in laptops and small form factor computers. SODIMMs are smaller and more compact than the larger DIMM modules used in desktop computers, making them well-suited for devices where space is limited. SODIMMs are used to provide additional random access memory (RAM) to a computer, allowing it to run more programs simultaneously and improving overall performance.
