Abstract
PURPOSE: To make it easy to point out a defective bit on the basis of byte parity when a fault occurs, even in case that a buffer memory unit and data matching circuit are increased in operation speed, by providing a memory unit with an address stack.
CONSTITUTION: A control signal for error occurrence suppresses storage in units following address stacks 9 and 10, which is reported to fault processor 1. Processor 1, having the method of reading address stacks 9-2 and 10-2, validates the contents of stack 9-2 to read the contents of buffer memory unit 11, and then validates the contents of stack 10-2 to read the contents of main memory unit 4, and after the logout address of a computer system is validated, data from units 11 and 4 are written in the logout area of unit 4. The contents of this logout area are read out and then compared with read data from units 11 and 4, so that a defective bit can be pointed out.
