    摘要： The invention is directed to a method of operating a control system which includes a nonvolatile memory unit having memory banks and a volatile memory unit for storing programs and data. Access is permitted to only a single one of the memory banks of the nonvolatile memory unit at a given time point and the memory bank permitting the access is addressable by using addresses which are located within a memory bank address space. The memory bank address space is common to all memory banks and adapted to the size of the memory banks. The nonvolatile memory and the volatile memory are driven in such a manner that the memory bank permitting the access is only accessible in part. When an addressing attempt is made via an address, which is assigned to that part of the particular memory bank which is not accessible, the volatile memory unit is shifted into a state permitting an access and the volatile memory is addressed via the address.

    摘要翻译： 本发明涉及一种操作控制系统的方法，该控制系统包括具有存储体的非易失性存储器单元和用于存储程序和数据的易失性存储器单元。 只允许在给定时间点访问非易失性存储器单元的单个存储器组，并且允许访问的存储体可通过使用位于存储器库地址空间内的地址来寻址。 存储体地址空间对于所有存储体来说都是共同的，并且适应于存储体的大小。 非易失性存储器和易失性存储器以允许访问的存储体仅部分可访问的方式被驱动。 当通过分配给不可访问的特定存储体的该部分的地址进行寻址尝试时，易失性存储器单元被转移到允许访问的状态，并且通过地址寻址易失性存储器。
