Abstract

PURPOSE:To improve the availability of a fault processing system by detecting the fault of a memory by a detecting means set into a processor which constitutes a data processing system together with plural memories and inhibiting the accesses to said faulty memory. CONSTITUTION:The fault of a memory 1 or 2 is detected by a memory fault detecting circuit 32 of a controller 3 based on the fault reports received from both memories 1 and 2. Then the fault is displayed in the bits corresponding to the memory fault display bits 33 and 34 in response to the detection signal of the circuit 32. At the same time, the corresponding AND gates 35 and 36 are closed so that the access is inhibited to the faulty memory 1 or 2. Thus it is possible to prevent the system breakdown due to the fault of the memory 1 or 2. Then the availability is improved for a fault processing system.
