In computing, double data rate (DDR) describes a computer bus that transfers data on both the rising and falling edges of the clock signal and hence doubles the memory bandwidth by transferring data twice per clock cycle.[1][2] This is also known as double pumped, dual-pumped, and double transition. The term toggle mode is used in the context of NAND flash memory.
