PURPOSE:To secure a prefixed area and eliminate the discontinuousness of floating addresses to realize the constitution of an address space, by setting automatically the own floating address in accordance with the states of other storage units. CONSTITUTION:A working checking circuit 8 checks the power supply definite state, the state of fault, etc. of an own storage unit 2 as well as the propriety of the normal working to deliver the state signal to a signal line 4. A floating address setting circuit 9 sets the floating addresses to floating address registers R1-Rn in accordance with the contents of the output of the circuit 8 and the tate signal supplied from a storage unit 3. For instance, the circuit 9 of the unit 2 set the floating addresses of R1-Rn by the general reset, etc. when the power sources of the units 2 and 3 are applied. On the other hand, a floating address setting circuit of the unit 3 also sets the floating address. |
