Cycle time is the time, usually measured in nanosecond s, between the start of one random access memory ( RAM ) access to the time when the next access can be started.Access time is sometimes used as a synonym (although IBM deprecates it). Cycle time consists of latency (the overhead of finding the right place for the memory access and preparing to access it) and transfer time. Cycle time should not be confused with processorclock cycles or clock speed , which have to do with the number of cycles per second (in megahertz or MHz ) to which a processor is paced.
