摘　　要：给出一种用ＲＡＭ扩充程序存贮器的方法，以及具体的硬件线路。这种简便实用的方法可为用户提供一种根据需要自行修改或编写应用程序的环境．A method of using random access memory to expand program memory is presentedwith its hardware implementation. For industrial intelligent products using single-chip microcomputers,this simple and practical method can provide an effective techique and environment for users to modify or rewrite application programs themselves according to requirements.This technique has been verified in application, and the problem that application programs in RAM will be lost when the power is off can be solved by suing a protective circuit.
