在计算机的应用中常常会遇到断电后需要保存一些数据的情况,特别是航空中经常需要把飞行中获取的数据拿到地面上进行处理,而采用磁带机可能会带来接口电路复杂、可靠性差、再现时间长等缺 Computer applications often encounter the need to save some data after power off, especially in aviation often need to get the data obtained in flight to the ground for processing, and the use of tape drives may bring interface circuit complexity, Poor reliability, reproduction of a long absence
