MODEL- CT2KT25664AC667    VENDOR- CRUCIAL TECHNOLOGY
    
FEATURES- 4GB kit (2GBx2), 200-pin SODIMM, DDR2 PC2-5300 memory module
       DDR2-PC5300, CL=5, UNBUFFERED, NON-ECC, DDR2-667, 1.8V, 256Meg x 64,
        200-pin SODIMM.
       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 SDRAM memory for notebook 
        computers. 200-pin SODIMMs are available in PC2100 DDR SDRAM, 
        PC2700 DDR SDRAM, and PC3200 DDR SDRAM. To use DDR memory, your 
        system motherboard must have 200-pin SODIMM slots and a DDR-enabled
        chipset. A DDR SODIMM will not fit into a standard SDRAM SODIMM 
        socket.
       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.
