A Small Outline Dual Inline Memory Module (SODIMM) consists of a number of memory components (usually Black) that are attached to a printed circuit board (usually Green). SODIMMs get their name because they are smaller and thinner than regular DIMMs. The gold pins on the bottom of the SODIMM provide a connection between the module and a socket on a larger printed circuit board. The pins on the front and back of a SODIMM are not connected.
