Crucial 1GB PC3200 200 pin SODIMM DDR Unbuffered Laptop Memory

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. 200 pin SODIMMs are used to provide DDR and DDR2 SDRAM memory for notebook computers. 200 pin SODIMMs are available in PC2700 DDR SDRAM, PC3200 DDR SDRAM, DDR2 PC2 6400 SDRAM, DDR2 PC2 5300 SDRAM, DDR2 PC2 4200 SDRAM and DDR2 PC2 3200 SDRAM. To use DDR or DDR2 memory, your system motherboard must have 200 pin SODIMM slots and a DDR or DDR2 enabled chipset. A DDR or DDR2 SODIMM will not fit into a standard SDRAM SODIMM socket. Information about which memory technology your system uses is included in the Crucial Memory Advisor™ tool. The number of black components on a 200 pin SODIMM can vary, but it always has 100 pins on the front and 100 pins on the back, for a total of 200. 200 pin SODIMMs are approximately 2.625 inches long and 1.25 inches high, though the heights can vary. Like 144 pin SODIMMs, 200 pin SODIMMs have one small notch within the row of pins; however, the notch on the 200 pin SODIMMs is closer to the left side of the module.
