PURPOSE:To recover and process the inverting trouble of a RAM used as an RCS cheaply and at high speed by providing a means to store the same data as the data (micro-instruction sequence) RCS (reloadable control storage)-loaded and a restarting address which goes to a pair with the data. CONSTITUTION:Together with the recovering data of RAM, a restarting address RADRi is prepared beforehand corresponding to a trouble address and by a channel control device CHC 300, a restarting processing corresponding to the trouble address can be executed to a channel device 3101-n. Namely, the instructing information to instruct the effect to restart after the CHC 300 sets the value to an address register ADR 312 together with the value of the RADRi fetched earlier to a data line 530 in continuation to the recovering processing of an RCS 311, is published and informed by a signal line 5101. |
