RAM Doubler: is DDR RAM headed for the Mac? (Mac Beat).

The falling price of memory chips forced RAM manufacturers to turn to Double Data Rate (DDR) RAM, which commanded higher prices than PC133 RAM. But now DDR RAM prices have dropped to about what PC133 RAM costs, making DDR RAM a more appealing option for computer makers. If this faster RAM finds its way into your Mac, it could mean a boost in performance.

DDR RAM transmits data on both the rise and the fall of the clock signal (the PC100 or PCl33 RAM in your Mac sends data on the rising edge).

That effectively doubles the bandwidth of the RAM, allowing the processor to ...
