Abstract
In an information processing apparatus, when error of an instruction read out from an instruction storage area is detected, a correct instruction is created and rewritten in the instruction storage area. The rewritten instruction is read out for undergoing again error detection. When error is again detected, decision is made as to whether the error is a fixed one. In the case of the fixed error, a correct instruction is stored in an alternative storage area, while a remedy pattern capable of evading that fixed error is written in the instruction storage area at an address location where the fixed error is detected. The correct instruction corresponding to the remedy pattern is read out from the alternative storage area.
