    Features of DDR3 Memory RAM

    DDR3 SDRAM Components:

    • First Introduction of asynchronous RESET pin
    • Support of system level flight time compensation
    • On-DIMM mirror friendly DRAM pin out
    • Introduction of CWL (CAS Write Latency) per clock bin
    • On-die I/O calibration engine
    • READ and WRITE calibration

    DDR3 Modules:

    • Fly-by command/address/control bus with on-DIMM termination
    • High precision calibration resistors
    • Are not backwards compatible-wrongly inserting a DDR3 module into a DDR2 socket can damage the DIMM and/or the motherboard
       
    Advantages compared to DDR2
     
    • Higher bandwidth performance, effectively up to 1600 MHz
    • Improved latencies as measured in nanoseconds.
    • Higher performance at low power (longer battery life in laptops)
    • Enhanced low power features
       
    Disadvantages compared to DDR2
     
    • Incompatible with DDR2 motherboards
    • As of January 2009, costs somewhat more than equivalent DDR2 memory
