Abstract

PURPOSE:To prevent system-down, by writing in a re-control information (micro- program) in the content of an RAM element in intermittent failure such as alpha-ray failure into the RAM through the use of a vacant time of a computer. CONSTITUTION:A control storages (CS) write-in device 4 loads or re-writes in from an external recorder 3 to a control storage device 100 during power-on or waiting state of a computer. In rewrite, a block number is set to a record number storage register 47 to the external recorder 3 via a signal line 402 by using a vacant time of the computer. Then, the instruction writing in the data from the external recorder 3 to the control storage device 100 is instructed with a signal line 303, which starts a control circuit 49, and the data in designated block is read out sequentially in one word unit for write-in. That is, the information of the control storage device can be maintained periodically, allowing to increase the system reliability.
