ABSTRACT:
Data are error protected; dual memory control is utilized. From one memory control only write-in data are transmitted in addition to address and control signals; from the other memory control only control data is transmitted. In the first case they are inputted into the user data segment of a segmented memory, while in the second case, they are inputted into the control data segment of the memory from whence they are both included into the data check. Thereby, address errors may also be recognized.
