摘要

The data are fault-tolerant, the memory controller (St0, St1) is doubled. Except the address and control signals, only the write data are forwarded by the one memory controller, and only the control data are forwarded by the other memory controller, and in the first case are written into the user data part (SPN) of a two-part memory and in the second case are written into the control data part (SPK) of this memory, from where they are jointly included in the data verification. As a result, it is also possible to detect address errors.
