wait stateThe time spent waiting for an operation to take place. Wait states are often idle computer cycles, because a computer's CPU is much faster than main memory. Wait states are introduced between the time the CPU requests data from the RAM (an address is placed on the address bus) until the content has been delivered to the CPU. See address bus.
