How does DDR work?

[Dputiger]

Can someone explain how DDR technology works? Thanks.

Double Data Rate SDRAM is little more than a small evolution of current SDRAM technology. DDR SDRAM is capable, like RDRAM, of transferring data on both the rising and falling edges of the clock cycle.

Short for Double Data Rate-Synchronous DRAM, a type of SDRAM that supports data transfers on both edges of each clock cycle, effectively doubling the memory chip's data throughput. DDR-SDRAM is also called SDRAM II source: www.pcwebopedia.com (http://www.pcwebopedia.com)
