Double data rate (DDR) memory is a type of synchronous dynamic random-access memory (SDRAM) that allows data to be transferred on both the rising and falling edges of the clock cycle, effectively doubling the data transfer rate compared to its predecessor, single data rate (SDR) memory. This design enhances overall performance and bandwidth, making DDR memory widely used in computers, graphics cards, and other devices. Different generations of DDR, such as DDR2, DDR3, DDR4, and DDR5, offer varying speeds and efficiencies.

What is Shared Dual Channel DDR2?

SD DDR2 Ram is a double data rate synchronous dynamic random access memory interface. In addition to double pumping the data bus as in DDR SDRAM, (transferring data on the rising and falling edges of the bus clock signal), DDR2 employs an I/O buffer between the memory and the data bus so that the data bus can be run at twice the speed of the memory clock. The two factors combine to achieve a total of 4 data transfers per memory clock cycle.
