It should be noted that the same or corresponding parts in the figures are indicated by the same reference numerals. Amendment March 22, 1980 - The scope of claims for utility model registration is amended as follows. O1 Utility Model Registration Scope of Claims 1.A memo blade that stores programs and data for electronic calculation, a memory buffer register that temporarily stores data read from this memory, and whether the data in the memory buffer register is correct or not. It is equipped with two parity error detection circuits for checking the parity error detection circuit and two frits buffers for holding the output of the parity error detection circuit, and a memory address register for specifying the memory address and a memory buffer register. an internal bus for data transfer, and a control memory and a control circuit for storing a microslot ram that controls these parts, and the data read from one of the E memories is If an error is determined by the circuit for one Validier, - the data read from the other memory in which the same content has been written is transferred via the circuit bus, and the incorrect memory content is removed. A memory device characterized in that the control of a microprogram is terminated by '.
