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.

144-pin SODIMMs are commonly found in notebook computers. 144-pin SODIMMs are available in EDO, 66MHz SDRAM, PC100 SDRAM, and PC133 SDRAM. When upgrading, be sure to match the memory technology that is already in your system. (Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool.)

The number of black components on a 144-pin SODIMM can vary, but it always has 72 pins on the front and 72 pins on the back, for a total of 144. 144-pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. They have one small notch within the row of pins along the bottom of the module.
