SODIMM

A SO-DIMM or small outline DIMM, is a smaller alternative to a DIMM, being roughly half the physical size of a regular DIMM.

SO-DIMMs are often used in systems that have limited space, which include laptops, notebooks, small-footprint personal computers such as those based on Nano-ITX motherboards, high-end upgradable office printers, and networking hardware such as routers and NAS devices.^[3] They are usually available with the same size data path and speed ratings of the regular DIMMs though normally with smaller capacities.
