　　A microprocessor clock cycle in which nothing occurs .A wait state is programmed into a computer system to allow other components ,such as random-access memory (RAM) ,to catch up with the central processing unit (CPU) .The number of wait states depends on the speed of the processor in relation to the speed of memory .Wait states can be eliminated—resulting in a "zero wait state" machine—by using fast (but expensive )cache memory ,interleaved memory ,page-mode RAM ,or static RAM chips.

　　等待状态

　　微处理器不执行任何动作的时钟周期。等待状态编入计算机系统中,以使其他部件(如随机RAM)跟上CPU的速度。等待状态的次数取决于与存储器速度相关的处理器速度。通过使用快速(但昂贵)的高速缓冲存储器、交错存取存储器、页面式RAM或静态RAM芯片,等待状态可消除,从而产生“零等待状态”机。
