    摘要: An external memory interface includes an input/output (IO) logic unit operable to convert a rate of data from a first rate corresponding to a memory controller/schedule unit to a second rate corresponding to an external memory device. The external memory interface also includes a latency adjustment unit, operating in a timing domain of the memory controller/schedule unit, operable to add between 1 to [(second rate/first rate)−1] cycles of latency of the second rate.
