<p><P>PROBLEM TO BE SOLVED: To correct a fault part even when the fault part is generated in a program which is stored in a memory, and to allow the memory storing the program to have an initial value. <P>SOLUTION: A read-only first memory 12 receives a user program from an outer terminal 10a and previously stores the program to be stored in an internal memory 15. A rewritable second memory 13 stores patch data where the fault part of the program is corrected. A data selecting circuit 14 inputs the program and patch data, which are outputted by an address signal, and generates the program with the fault part corrected therein. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
