Crucial CT25664AC800 2GB DDR2 PC2-6400 Memory Module

200-pin SODIMMs are used to provide DDR and DDR2 SDRAM Memory for Notebook computers. A small outline dual inline memory module consists of a number of memory components that are attached to a printed Circuit board. 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.
