Currently, DDR SDRAM cannot keep pace with the demands of these new CPU’s and high performance system components. The PC industry has been planning for this eventuality by developing a new specification for DDR memory enabling it to scale to higher frequencies. This successor named DDR II is still a few years away with samples expected in 2004. The DDR ‘II’ specification already agreed by JEDEC, redesigns both the DDR device and the module interface, meaning that DDR ‘II’ mainboards will not be backwards compatible with standard DDR modules. This leaves us with a current technology that cannot keep up and a future technology that requires a major redesign and upgrade. Enter stage left… Quadband DDR.
